45amp Junction Box?

[steamvalve]

I need to re-route an electric shower cable. The shower is 9.5kW and the shower switch is 45 amp. I can only find 30 amp junction boxes in B&Q. Do 45amp junction boxes exist?

 

[breezer]

yes, try tlc (no one says you can use bigger either)

TLC don't do 45A, but they do 60A.

I need to re-route an electric shower cable.

Where are you thinking of putting the junction box?

Its never recommended that you put junction boxes on a circuit with such a high single load. I'd renew the whole length of cable or use crimps.

Steve, a junction box is only a triple-pole switch without the extra resistance of the contacts.

Would you not agree that it's ok as long as the box remains accessible?

I was going to say more or less the same.Although in an ideal world a complete cable is better, there is nothing wrong with a correctly installed junction box.

The problem with crimps is that done properly they are a very good joint, but if they arn't then it can be a very poor joint. Anyone with a decent set of handtools that takes their time and understands the importance of getting the terminals tight can make a reasonable joint using a jointbox. With crimps you need a decent pair of crimpers which a fair few quid and you need to be able to recognise that the joint hasn't gone pear shaped (and the best way to be able to do that, is a bit of scrap cable, some connectors and a vice, practice joining cable and pulling it apart, and you'll get a feel for it)
