In the UK, under the IET Wiring Rules 17th Edition (now in force), all new domestic (and most industrial) 230V socket-supply outlets and lighting circuits must be protected by Residual Current Devices (RCD) ~ GFCI.
OTOH, rating is typically 30mA with the IEC/EN time-current characteristics, so nuisance tripping is rare – certainly haven’t had that at home on circuits to which many SMPU devices (with filters) are connected. And it has saved me from the odd-shock!!

To require one for every branch circuit in a home seems excessive. _____________________________________________________________________________________ Ralph McDiarmid | Schneider Electric | Renewable Energies Business | CANADA | Regulatory Engineer From: Doug Smith <d...@emcesd.com> To: EMC-PSTC@LISTSERV.IEEE.ORG List-Post: emc-pstc@listserv.ieee.org List-Post: emc-pstc@listserv.ieee.org List-Post: emc-pstc@listserv.ieee.org Date: 07/27/2010 09:30 PM Subject: Re: [PSES] GFCI Outlets in Phoenix, AZ ________________________________ Hi Scott, Computer equipment should, in my opinion, never be used on a GFCI circuit. The leakage current in the EMI filter biases the GFCI almost to the trip point in some cases and any little disturbance may trip it. I have observed this first hand where turning on a light at the far end of the house would trip a GFCI outlet in the kitchen (on a different circuit about 100 feet of wiring away) that had a microwave oven plugged in. This could cause serious problems for a computer. I have stopped electricians from putting GFCI outlets in many circuits of my home for this reason when I had the house rewired (I need 200 Amps for all my goodies, peak of course). Separately, I recommend techies to see the new movie "Sorcerers Apprentice." I can identify with the lead actor as I suspect many on this list can.

Don’t have much more to go on other than they may also have a limit of 1,000 W for these outlets. Please somebody tell me it ain’t so. Or worse, please tell me the details. Thanks for any comments.
