Default Re: Old electrical fittings


This posting is of interest to me as I need information about when shutters on socket outlets were first used.

Unfortunately, the pictures are not close enough for me to see which sockets have shutters, if any.

Can anyone help me find out when shutters were first used please? I need verifiable information, so it would have to be backed by catalogues, standards or similar.

I know that shutters were considered essential by the Post War Buildings Studies Committee who published their report, No. 11 - Electrical Installations in 1944. This led to BS 1363 for 13A sockets which have thus always had shutters. However they were recommended in the 11th edition of the Wiring Regulations first published in 1938 and so it would seem that they were used before then.

(If this enquiry is not relevent to this thread, could it please be moved to a new one)?
