Joining 6mm

I thought thermal imagining cameras were designed to be sensitive, so you can see for example where the heat is leaving your house?

I have no idea how sensitive they are, but would doubt that they (at least, of the type that an electrician might have) are necessarily sensitive enough to detect very small differences in temperature,

Also there must be heat generated under high load in the cables let alone the connections as copper has a good resistance and we only limit it to 70c in PVC. If it didn't heat up how would screw terminals on cooker circuits loosen themselves.

Yes, but you're now talking about something very different, and essentially irrelevant to the question being discussed. If, by virtue of the current flowing through them, all of the conductors entering the JB were at 70°C, then, if there were not a lot of heat losses, then all of the terminals in the JB would eventually have a temperature of 70°C. However, that's true whether there are 3, 4 or even 40 such cables (all at 70°C) going into the JB - so can't be the reason why a 4-'terminal' J803 is said to have a much lower maximum current capability that a 3-terminal' J804. Only if substantial amounts of heat were being generated at/by the terminals (which just shouldn't happen) would the number of terminals be relevant to the 'current rating' of the JB.

Kind Regards, John

The ones sold round here have all "white" terminals
Is that an old first edition one
The newer ones seem to have an install leaflet

?? They are black cos of the fire.
I have the leaflet, but most of it can't be read because it got burned.

If it didn't heat up how would screw terminals on cooker circuits loosen themselves.

I used to install and repair white goods, I've not come across this problem before?

D'you know, all this time and I didn't realise you had an ES lamp in your mouth, husky!

They look transparent, Before you burnt them

How could you miss it, it's GES and about 30cm long! It's a 1KW GLS lamp.
It lights up with husky power!

They are burnt in all the pics, they started off white. The buttons burnt differently to the main part of the connector.

I guess you screw it in with your mouth, as your paws must be pretty useless for dextrous tasks...

Nicely priced, Lewden is.

Nicely priced, Lewden is.

For a reason!!

It is reliable and has had no recalls, loads of room in the enclosure, the AM3 boards are much better than the plastic ones. We used to use MK but ditched them after all the faults and recalls. Besides I don't get to choose!
