Re: [PSES] EMC/EMI Cables

There is a company called Sewelldirect that used to provide a well shielded HDMI cable. They had a webpage on the subject. However, I can't find it on their website anymore. Apple sell a properly shielded HDMI cable. BR John McAuley From: Ken Wyatt Sent: 29 April 2021 15:54 To: EMC-PSTC

Re: [PSES] Safety design of shutter opening

Hi Scott Ireland uses the same plug as the UK as per I.S. 401:1997 - Safety Requirements For Rewireable And Non-rewireable 13A Fused Plugs. IS 401 is the equivalent of BS 1363. Interesting issue about plugs being able to be inserted upside down in some extension sockets. John

Re: [PSES] Audio Frequency Induction Loop
