can you crimp multiple live wires

[JamesAsus]

Hi all,

I'm wanting to fit light fittings in most of the rooms in my house. Had a bit of a nightmare with the one room I have done as the wires coming out of the ceiling were so short I ended up having to keep them in the existing ceiling rose and place the fitting over this, which was awkward to say the least.

My question is, is it ok to have crimps in the ceiling void/in the light fitting itself? Also choccy blocks, are these ok to use to extend wires as long as they are accessible when you remove the fitting? or is it a melt risk If the fitting gets warm from the bulbs for example?

Also can I ask, this may be a very basic question but how do you know how many amps a circuit has? I know the light I fitted was on a 6 amp circuit/fuse as it says on the rose itself.

My question is, is it ok to have crimps in the ceiling void/in the light fitting itself?

Opinions vary as to whether it's OK to use crimps on solid conductors in the first place.

They should not be in the ceiling void unless enclosed in a box - basically there should never be any cables with exposed lack of outer sheath.

Also choccy blocks, are these ok to use to extend wires as long as they are accessible when you remove the fitting?

Ditto enclosure requirement.

With both crimps and choc, being inside a light fitting will be OK.

or is it a melt risk If the fitting gets warm from the bulbs for example?

Could be - depends where the choc-block is wrt parts of the light which get hot.

Also can I ask, this may be a very basic question but how do you know how many amps a circuit has?

Circuits don't "have" a certain number of amps. They have a certain capacity. It's a bit like asking "how many MPH does a road have?"

I know the light I fitted was on a 6 amp circuit/fuse as it says on the rose itself.

Ask yourself if what it says on the rose would change if you connected it to a different sort of circuit.
