where can you buy an isolator switch ?

[Norv]

Could someone advise me where you can buy the 100a isolator switches from that go between the electric meter & the CU (to isolate the CU without having to pull the main fuse). The ones I've seen on the TLC website are the ones that go in the CU.

Thats the one you need it fits inside a 2-module DIN rail enclosure to form the isolator switch between the meter and the CU

ok thanks. I know MEM do one but I couldnt find it.

Yeah thats the one JohnD. The purple one is the easiest to fit....

Any good http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=A331831&ts=84228&id=32311 & http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=A331832&ts=84384&id=53010

looks fine. the MEM enclosure has the added feature that you can remove a separate hatch over the load-side terminals to instal new tails, without exposing the supply side terminals (even if it has been wire-sealed)

(see my pic, second from the right)

For mains tails, I find this better http://www.screwfix.com/app/sfd/cat...436&cm_re=CROSS_SELL-_-SLOT4-_-74436&ts=20444 simply because the casing is sturdier & wider. The 2 module enclosures are very flimsy.

This is mine, fitted myself. Ignore the exposed insulation where the tails go into the meter - Norweb did that bit...

Edit: Yikes, that's large!! Let's try again...

 

[JohnD]

you're right, it does look like a sturdier case. I somethimes think those cream ones aren't enough for a big heavy switch with huge cables.

To be fair, the MEM one isn't bad. The Wylex one is OK too, but much wider. And the screws' heads strip easily.

One finishing touch to that big main switch in a hinged enclosure.

Fixing a label on it marked "MAIN SWITCH - WHOLE HOUSE" would be a good idea, especially if there is more than one consumer unit fed from the tails, as in my case.
