wiring a commercial dishwasher

[Innominata]

Hi Guys,
I am going to install a 7kw commercial dishwasher.This will be a new circuit,does the following installation method sound ok:fit C32 amp MCB to a spare way on the board,wire from the board in 6mm twin and earth to a junction box which will be next to the board and finally to a rotary isolator placed under the junction box.Thanks for any advice.

Why a junction box ?

How are you running the cable, distance from DB, volt drop etc are other questions you should look at as well.

Hi,
re previous post.I will be able to install without a junction box.I intend to put the isolator directly under the DB,drilling a 20mm hole into the DB and using a coupler and bush to connect the isolator.Volt drop will not be a problem as the cable will come directly out of the DB via the coupler into the isolator total length about 18 inches. Does this sound ok?
