Help, shower cable overheating

[Lucien Nunes]

12kw 100m from the board will get the cable hot

Eh? longer cable... more resistance... lower current... cooler cable...

Have you calculated the correct cable size for the shower and distance? 12kw 100m from the board will get the cable hot

Hmmm, not really but volt drop might become an issue.

Thry didn't teach me that at college and every sparky I've worked alongside has just used normal screwdrivers. Must see if I can get one

They did not teach me that either but I am aware that people use them, I have never seen a electrician useing them not one, I would like some my self but cant justify the price

I think it stems from manufacturers instructions in CUs and following them in the regs bollox.

I wouldn't mind trying one, just to compare the tool torque v wrist action actually.

I to would be interested in finding that out.
Am I to heavy handed or to light.....
I suspect heavy handed but I have not had any loose connection problems yet so i guess ime not doing to badly.....

what would be the correct torque setting in ft pounds ideally, for the 10mm cable terminal screw?

About quarter past three!

thats the answer i expected

I'd have a read of Telectrix's posts about normal warming of cables? A shower cable can get hot depending on how much current is going through it, although if it is that then you would expect the line to be hot as well.

Also, accredited cables, Basec etc, are rated at up to 70c which would feel pretty hot!

Can you keep your hand on it? Is the DP switch getting hot? Does the line conductor get hot? What kW is the shower?

ps... after second thoughts dont try and keep your hand on the neutral in a live CU!!!!
