He could take the 5 core to one CU and feed the shower from there.
It would be bad practice to have a circuit in the CU which is not isolated by the mainswitch of the CU.

Use a contactor or a 3 pole main switchIt would be bad practice to have a circuit in the CU which is not isolated by the mainswitch of the CU.
do you think 10mm would work?

Using a 3 pole mains switch would isolate all circuits.I don't see how that will help.
a contactor will normally turn off a circuit but i would not consider it isolated.Using a 3 pole mains switch would isolate all circuits.
Using a contactor would isolate the outgoing shower circuit.
Using a CT relay at the House would mean you could also limit other circuits if there was lack of capacity.
Why not ?a contactor will normally turn off a circuit but i would not consider it isolated.
What term did I use that was wrong ?not trying to be pedantic but we should use the correct terms for things as professionals so that we leave nothing to the imagination or interpretation of our words.
unless of course you think a contactor is a suitable means of isolation and then i would just call you out as Wrong.
Ok.
I'm thinking a contactor has a control circuit, which would operate said contactor. Whereby you could isolate the control circuit. But does that safely isolate the circuit, like a standard isolator would do. What does BS7671 say about isolation?
