volex rcd

[SPARTYKUS]

hi

just a quick one,

as far as I'm aware, RCD's (with two poles, specifically the VOLEX VR80 30mA) don't care which side the Line or Neutral go in.

Am I right?

Or is this model a special case?

Can't think why, I know it works on an inbalance betwixt L-N, and the bumpf says you can wire it up either way, horizontally or vertically.

EDIT : when I say either way I mean the feed can go in the top or bottom.

?

thats fine...!! its double pole so polarity is not a problem!

Depending on how the test function has been implemented, wiring it the wrong way around could cause the test function to either not work at all or create a phase-earth fault the wrong side of the RCD which obviously isn't protected.

Edit: Scratch that. It only applies to old school devices that don't have a test coil wound on to the toroid.
