Insulating Wire Ends

[Jeff Gaines]

I have replaced an old wall thermostat with Honeywell TR 3 (on excellent advice from this group) which works brilliantly. It is a simple on-off switch and I have a spare neutral and earth in the backplate which I don't want to cut off as a future upgrade might need them.

I need to insulate them and wondered if something like these wire caps would work:

They seem to be designed to take two wires, I need to insulate these two wires separately, when they touched accidentally my RCD tripped as quick as a flash which I believe is WAD?

Are these caps any good? If not any other suggestions please?

Just get a two gang piece of choc block.

not legal for mains house wiring usual chocblock should do it

Choc block or better still wago 221

Possibly expensive from Screwfix etc. because you need to by quantities of 25+

Smaller quantities on Ebay (but shop around) First Ebay hit

Or put a crimp connector on each wire, leaving the free end uncrimped ready to connect another wire if you ever need to.

put heatshrink on them

or 2 x one-gang if space is tight. (I was there late Friday night rescuing a neighbour by isolating part of a kitchen ring which was tripping her RCD.)

downside with crimps is that you can't easily remove them and cutting them off may leave the wires too short

There may not always be room for that though. I cannot see the ones suggested, but back in them good old days, Tandy used to make close ended sleeves that were quite flexible but strong. a bit of superglue and the right size and the job was done. They were a bit like those slide on toggle switch coloured sleeves you can get, but longer. Brian

But DONT put both wires into a single Wago 221, you will need two separate ones. Unlike chock block a Wago will short both wires together.

Many thanks for all the replies :-)

Choc block it will be so that the wires are available >Are these caps any good? If not any other suggestions please?

Use a blind shrink-on cap

Squirt some silicone sealant over the ends of the choc block, easy enough to dig out when/if the time comes.

That's a bit OTT. Green yellow insulation tape is what the op needs:-(

[ARW]

Just put both cables to earth at both ends with some green yellow over sleeving

Or as found in my mothers house when she purchased it - connections made by just twisting the wires together and insulated with Sellotape.
