100A isolator?

Nov 02, 2003 7 Replies

I'm in the process of rewiring the house, and having noted all the comments, would like to fit a 100A isolator.



I'd just like some comments on this:



Isolator placed between meter and Henley block (there's a Henley block on the end of the meter tails already, although it's a bit small and I will be replacing it). From the Henley block, tails to two or three consumer units (it's a tall narrow space, so I can't get a bigger CU in there).



If that's OK, next question. Can anyone recommend a source for a suitable isolator? All I've found is a 2 or 4 position consumer unit box with a 100A DP switch in it....perhaps I'm looking at the wrong suppliers (RS, TLC, CPC). If that is a reasonable solution, presumably I ignore the busbar and just wire into top and bottom of the switch...

The Wylex 100A switchfuse is at

a 3-phase switch only is actually half the price

one phase for L and one phase for N and *label the terminals*

Yes, considered that...would be fairly reasonable as it's a 4 terminal cutout...outer left for L and outer right for N...

Thanks...

That's (nearly) the cheapest way to do it - you can get DIN boxes without busbar from CPC & a bare 100A DP switch for approx £14 I use them for mounting 63A x 100ma DP Switch/RCDs.

no more that £50-60 IIRC.

That may be the solution. The Wylex one is nice, but it's also rather large in the limited space I have.

How about: RS 419-555 100A Switch disconnector 8quid+vat RS 341-4632 Terminal Cover 3quid+vat - includes a din rail to mount the switch. Small & cheap

Thanks...looks roughly equivalent to the CPC thing mentioned before. Guess it'll be from whoever I next place an order with!
