Dear Sirs

Cooper Industries, Ltd. (the “Company”)

We have acted as legal counsel in Bermuda to the Company in connection with the Registration Statement to be filed by the Company as registrant (the “Registrant”), Cooper B-Line, Inc., Cooper Bussmann, Inc., Cooper Crouse-Hinds, LLC, Cooper Lighting, Inc., Cooper Power Systems, Inc., Cooper US, Inc. and Cooper Wiring Devices, Inc. as co-registrants (together the “Co-Registrants”) relating to the shelf registration under The Securities Act of 1933, as amended, of debt securities of Cooper US, Inc. (the “Debt Securities”) and guarantees (the “Guarantees”) of the Registrant and Co-Registrants other than Cooper US, Inc.

For the purposes of this opinion we have examined and relied upon the documents listed, and in some cases defined, in the Schedule to this opinion (the “Documents”) together with such other documentation as we have considered requisite to this opinion.

Assumptions

In stating our opinion we have assumed:

(a)	the authenticity, accuracy and completeness of all Documents and other documentation examined by us submitted to us as originals and the conformity to authentic original documents of all Documents and other such documentation submitted to us as certified, conformed, notarised, faxed or photostatic copies;
(b)	that each of the Documents and other such documentation which was received by electronic means is complete, intact and in conformity with the transmission as sent;

(c)	the genuineness of all signatures on the Documents;
(d)	the authority, capacity and power of each of the persons signing the Documents (other than the Company in respect of the Subject Agreements);
(e)	that any representation, warranty or statement of fact or law, other than as to the laws of Bermuda, made in any of the Documents is true, accurate and complete;
(f)	that the Subject Agreements will constitute the legal, valid and binding obligation of each of the parties thereto, other than the Company, under the laws of its jurisdiction of incorporation or its jurisdiction of formation;
(g)	that the Subject Agreements have been validly authorised by each of the parties thereto, other than the Company, and that, when executed and delivered, the performance thereof will be within the capacity and powers of each such party thereto, and that each such party to which the Company purportedly delivers the Subject Agreements will have actually received and accepted delivery of such Subject Agreements;
(h)	that the Registration Statement has been validly authorised and executed by each of the Co-Registrants.
(i)	that the Subject Agreements will effect, and will constitute legal, valid and binding obligations of each of the parties thereto, enforceable in accordance with their terms, under the laws of the State of New York by which they are governed;
(j)	that the Subject Agreements are in the proper legal form to be admissible in evidence and enforced in the courts of the State of New York and in accordance with the laws of the State of New York and that the Subject Agreements do not create a charge or lien over the assets of the Company under the laws of the State of New York;
(k)	that there are no provisions of the laws or regulations of any jurisdiction other than Bermuda which would be contravened by the execution or delivery of the Subject Agreements or which would have any implication in relation to the opinion expressed herein and that, in so far as any obligation under, or action to be taken under, the Subject Agreements is required to be performed or taken in any jurisdiction outside Bermuda, the performance of such obligation or the taking of such action will

constitute a valid and binding obligation of each of the parties thereto under the laws of that jurisdiction and will not be illegal by virtue of the laws of that jurisdiction;

(l)	that none of the parties to the Subject Agreements maintains a place of business (as defined in section 4(6) of the Investment Business Act 2003), in Bermuda;
(m)	that the records which were the subject of the Company Search were complete and accurate at the time of such search and disclosed all information which is material for the purposes of this opinion and such information has not since the time and date of the Company Search been materially altered;
(n)	that the records which were the subject of the Litigation Search were complete and accurate at the time of such search and disclosed all information which is material for the purposes of this opinion and such information has not since the time and date of the Litigation Search been materially altered;
(o)	that the Resolutions are in full force and effect, have not been rescinded, either in whole or in part, and accurately record the resolutions passed by (i) the Board of Directors of the Company in a meeting which was duly convened and at which a duly constituted quorum was present and voting throughout and (ii) the Committee, as appointed by the Board of Directors of the Company, in a meeting which was duly convened and at which a duly constituted quorum of the Committee was present and that there is no matter affecting the authority of the Directors or the Committee to effect entry by the Company into the Subject Agreements, not disclosed by the Constitutional Documents or the Resolutions, which would have any adverse implication in relation to the opinions expressed herein;
(p)	that the Company will enter into its obligations under the Subject Agreements in good faith for the purpose of carrying on its business and that, at the time it does so, there will be reasonable grounds for believing that the transactions contemplated by the Subject Agreements will benefit the Company;
(q)	that each transaction to be entered into pursuant to the Subject Agreements is entered into in good faith and for full value and will not have the effect of preferring one creditor over another; and

(r) that, when executed and delivered, the Indenture will be in a form which does not differ in any material respect from the draft which we have examined for the purposes of this opinion.

Opinion

Based upon and subject to the foregoing and subject to the reservations set out below and to any matters not disclosed to us, we are of the opinion that:

(1)	The Company is an exempted company incorporated with limited liability and existing under the laws of Bermuda. The Company possesses the capacity to sue and be sued in its own name and is in good standing under the laws of Bermuda.
(2)	The Company has the corporate power and capacity to issue the Guarantees as contemplated by the Registration Statement.
(3)	The guarantee, as contemplated by the Company in Article Sixteen of the Indenture, will, upon the due execution by the Company of the Indenture to which the Company is a party, constitute legal valid and binding obligations, enforceable against the Company in accordance with its terms.
(4)	The Registration Statement to which the Company is a party has been duly executed by the Company and constitutes legal valid and binding obligations, enforceable against the Company in accordance with its terms.
(5)	The issue of the Debt Securities will not violate, conflict with or constitute a default under (i) any requirement of any law or any regulation of Bermuda or (ii) the Constitutional Documents.
(6)	The Company has received an assurance from the Ministry of Finance granting an exemption, until 28 March 2016, from the imposition of tax under any applicable Bermuda law computed on profits or income or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, provided that such exemption shall not prevent the application of any such tax or duty to such persons as are ordinarily resident in Bermuda and shall not prevent the application of any tax payable in accordance with the provisions of the Land Tax Act 1967 or otherwise payable in relation to land in Bermuda leased to the Company. There are, subject as otherwise provided in

this opinion, no Bermuda taxes, stamp or documentary taxes, duties or similar charges now due, or which could in the future become due, in connection with the execution, delivery, performance or enforcement of the Subject Agreements or the transactions contemplated thereby, or in connection with the admissibility in evidence thereof and the Company is not required by any Bermuda law or regulation to make any deductions or withholdings in Bermuda from any payment it may make thereunder.

Reservations

We have the following reservations:

(a)	The term “enforceable” as used in this opinion means that there is a way of ensuring that each party performs an agreement or that there are remedies available for breach.
(b)	We express no opinion as to the availability of equitable remedies such as specific performance or injunctive relief, or as to any matters which are within the discretion of the courts of Bermuda in respect of any obligations of the Company as set out in the Subject Agreements. In particular, we express no opinion as to the enforceability of any present or future waiver of any provision of law (whether substantive or procedural) or of any right or remedy which might otherwise be available presently or in the future under the Subject Agreements.
(c)	Enforcement of the obligations of the Company under the Subject Agreements may be limited or affected by applicable laws from time to time in effect relating to bankruptcy, insolvency or liquidation or any other laws or other legal procedures affecting generally the enforcement of creditors’ rights.
(d)	Enforcement of the obligations of the Company may be the subject of a statutory limitation of the time within which such proceedings may be brought.
(e)	We express no opinion as to any law other than Bermuda law and none of the opinions expressed herein relates to compliance with or matters governed by the laws of any jurisdiction except Bermuda. This opinion is limited to Bermuda law as applied by the Courts of Bermuda at the date hereof.

(f)	Where an obligation is to be performed in a jurisdiction other than Bermuda, the courts of Bermuda may refuse to enforce it to the extent that such performance would be illegal under the laws of, or contrary to public policy of, such other jurisdiction.
(g)	We express no opinion as to the validity, binding effect or enforceability of any provision incorporated into the Subject Agreements by reference to a law other than that of Bermuda, or as to the availability in Bermuda of remedies which are available in other jurisdictions.
(h)	Where a person is vested with a discretion or may determine a matter in his or its opinion, such discretion may have to be exercised reasonably or such an opinion may have to be based on reasonable grounds.
(i)	Any provision in the Subject Agreements that certain calculations or certificates will be conclusive and binding will not be effective if such calculations or certificates are fraudulent or erroneous on their face and will not necessarily prevent juridical enquiries into the merits of any claim by an aggrieved party.
(j)	We express no opinion as to the validity or binding effect of any provision in the Subject Agreements for the payment of interest at a higher rate on overdue amounts than on amounts which are current, or that liquidated damages are or may be payable. Such a provision may not be enforceable if it could be established that the amount expressed as being payable was in the nature of a penalty; that is to say a requirement for a stipulated sum to be paid irrespective of, or necessarily greater than, the loss likely to be sustained. If it cannot be demonstrated to the Bermuda court that the higher payment was a reasonable pre-estimate of the loss suffered, the court will determine and award what it considers to be reasonable damages. Section 9 of The Interest and Credit Charges (Regulations) Act 1975 provides that the Bermuda courts have discretion as to the amount of interest, if any, payable on the amount of a judgment after date of judgment. If the Court does not exercise that discretion, then interest will accrue at the statutory rate which is currently 7% per annum.
(k)	We express no opinion as to the validity or binding effect of any provision of the Subject Agreements which provides for the severance of illegal, invalid or unenforceable provisions.

(l)	A Bermuda court may refuse to give effect to any provisions of the Subject Agreements in respect of costs of unsuccessful litigation brought before the Bermuda court or where that court has itself made an order for costs.
(m)	Searches of the Register of Companies at the office of the Registrar of Companies and of the Supreme Court Causes Book at the Registry of the Supreme Court are not conclusive and it should be noted that the Register of Companies and the Supreme Court Causes Book do not reveal:

(i)	details of matters which have been lodged for filing or registration which as a matter of best practice of the Registrar of Companies or the Registry of the Supreme Court would have or should have been disclosed on the public file, the Causes Book or the Judgment Book, as the case may be, but for whatever reason have not actually been filed or registered or are not disclosed or which, notwithstanding filing or registration, at the date and time the search is concluded are for whatever reason not disclosed or do not appear on the public file, the Causes Book or Judgment Book;
(ii)	details of matters which should have been lodged for filing or registration at the Registrar of Companies or the Registry of the Supreme Court but have not been lodged for filing or registration at the date the search is concluded;
(iii)	whether an application to the Supreme Court for a winding-up petition or for the appointment of a receiver or manager has been prepared but not yet been presented or has been presented but does not appear in the Causes Book at the date and time the search is concluded;
(iv)	whether any arbitration or administrative proceedings are pending or whether any proceedings are threatened, or whether any arbitrator has been appointed; or
(v)	whether a receiver or manager has been appointed privately pursuant to the provisions of a debenture or other security, unless notice of the fact has been entered in the Register of Charges in accordance with the provisions of the Act.

Furthermore, in the absence of a statutorily defined system for the registration of charges created by companies incorporated outside Bermuda (“overseas companies”) over their assets located in Bermuda, it is not possible to determine definitively from searches of the Register of Charges maintained by the Registrar of Companies in respect of such overseas companies what charges have been registered over any of their assets located in Bermuda or whether any one charge has priority over any other charge over such assets.

(n)	In order to issue this opinion we have carried out the Company Search as referred to in the Schedule of this opinion and have not enquired as to whether there has been any change since the time and date of such search.
(o)	In order to issue this opinion we have carried out the Litigation Search as referred to in the Schedule to this opinion and have not enquired as to whether there has been any change since the time and date of such search.
(p)	In opinion paragraph (1) above, the term “good standing” means that the Company has received a Certificate of Compliance from the Registrar of Companies.
