On one occasion, some UK engineers told me that a small group of house in UK and EU still do not have such 32A breaker installed. Thus the equipment complying with LVD Directive may not be safe in abnormal operation.

A large number (there is a limit but it's complicated) of 13 A wall outlets can be connected to this ring, relying on diversity to keep the total current below 32 A. With best wishes DESIGN IT IN!

Ralph McDiarmid Product Compliance Engineering Solar Business Schneider Electric From: Richard Nute [mailto:ri...@ieee.org] Sent: Saturday, December 03, 2016 12:01 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] British question, about a BS1363 plug-in power supply I understood the fuse in the U.K. plug was to protect the power cordage. In the U.K., outlets are supplied by a ring circuit rather than a branch circuit, therefore the power cord could exceed its ampacity (a U.S.A. term). So, if no power cord, no need for a fuse in the plug. I wonder if the power supply has a fuse to protect the power supply. If so, would this count as the plug fuse? Rich From: John Woodgate [mailto:jmw1...@btinternet.com] Sent: Saturday, December 03, 2016 5:01 AM To: mailto:EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] British question, about a BS1363 plug-in power supply I received a 5 W SMPS plug-in power supply as part of a multi-unit product. It has interchangeable pins for EU, US, Australian and UK sockets, but it has no fuse. I think this is illegal and intend to notify Trading Standards, as the overall product is marketed by a prominent European company and is widely offered on the Internet. Is there any exemption at all for the requirement that a BS 1363 plug in any form must have a fuse? - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
