Wiring question

So I have two wires side by side inside the connector. The screws are clamping the wires together. That's the low resistance path. There is a higher resistance one, where the current leaves one wire, flows into the connector, then back into the other wire - but surely it'll not be carrying much current? At a guess a third? Which might be OK for a smaller connector designed to take a current where the wires aren't touching?

That?s very arguable indeed given that the two wires have much more contact area between the wire and the inside of the hole in the connector than between the wires.

If you were designing an appliance and the connections were always done th is way, a downrated connector could be justified. Though if you think no cu rrent would flow through then you're not skilled enough to do that.

Probably. Maybe they don't even touch each other.

You don't know the relevant resistances, you're merely guessing. A solid bl ock of conector metal is in fact very low resistance. The wire to wire resi stance is variable.

Can you use a 20A junction box on 32A final ring circuit to join two cables together?

Physically you can use all sorts of things, but it ain't compliant on a 32A circuit.

Unless you are unable to use a screwdriver then I would not worry about using strip connector:-)

Ta:-))))))))))

I always feel *slightly* safer with soldered and heat shrunk, even though I have a fairly good ratchet crimper.

Thankfully the screwdriver was in good working order. The next stage is an inspection by an electrical engineer (retired and enjoys a curry) later today :-) .

Are you currying favour?

I'll get me coat.

Nothing is as good in my experience as a decent ratchet crimper and decent crimp terminals never had a problem with them ever:)!..

Not rising to the bait then?

JOOI if you replaced a double socket would you have that inspected?

Well, he's with me now since you mention it :-)

And no, I was not being entirely serious. I've done quite a bit of minor electrics over the years (including replacing a double socket recently).

My friend is doing present job because it involves rerouting the ring main, channeling and entering the consumer unit. Also, he has much better tools than me !!!

Solder can be very good - so long as the joint is mechanically supported well enough.

Crimps are easier to deploy in the field usually, and don't have the mechanical support worry.

In fact, I excelled myself. We dropped the inspection light and M said it was 'buggered' because it was LED. I was sceptical, checked and found it was only a battery dislodged.

I think he is following my wiring plan rather than his because it involves much less work !!!
