§ MR. T. LOUGH (Islington, W.)I beg to ask the President of the Board of Trade whether the Board of Trade have approved any meter for the electric light; whether it is necessary that such meters should be submitted periodically to any local authority for testing purposes; and, 271 what is the margin of error which the Board of Trade will allow in such meter?
§ THE PRESIDENT OF THE BOARD OF TRADE (Mr. C. T. RITCHIE,) CroydonThe Board of Trade have approved the pattern and construction of two electricity meters for use generally for the measurement of electrical quantity when supplied on the constant pressure continuous current system, and of one meter for use in certain Metropolitan districts for the measurement of electrical quantity when supplied on the alternating current system. There is no statutory provision that such meters shall be submitted periodically to a local authority for testing purposes. Under the Provisional Orders granted under the Electric Lighting Acts it devolves on local electric inspectors to certify meters used otherwise than by agreement to be correct, and to be of some pattern and construction approved by the Board of Trade. This being so, there is no question of margin of error allowed by the Board of Trade.
