Subject: Re: Surge Protection EN 60439-1
I read in !emc-pstc that Kevin Richardson kevin.richard...@ieee.org
wrote (in nebbihdflagbliikmlbkgeabdnaa.kevin.richard...@ieee.org)
about 'Surge Protection EN 60439-1' on Tue, 3 Dec 2002:
Can anyone please advise if EN 60439-1 allows the practice of placing a
surge protection device (eg an MOV) across the mains input (active to
earth)
is accepted.
The MOV would probably be set at something like 420 vAC or RMS so probably
about 600 peak.
Whether it does or not, DON'T DO IT! It's now considered dangerous.
There is alleged to be an exemption for hard-wired equipment (not plug-
in) with tow separate earth paths back to the fusebox (which a British
ring-main does automatically, but not a spur), but I've not seen any
official text yet.
