40A Isolator MetalClad or ABS

[Spike1947]

Hi
I am wanting to purchase a Metal Clad or ABS 40A RCD/MCB isolator to feed a 40 Tube Sun bed, not quite sure whether to get just the 40A RCB or get a 63A RCB with a 40A MCB , something on the lines as per pics shown, I need it to be as small a foot print has possible.

cheers

Have you worked the loading out before you asking this question.

Yes

Obviously an RCD doesn't provide overcurrent protection, so if this enclosure is to be fed by an overcurrent protective device, then just an RCD is all you need.
Otherwise, your enclosure will need to have either an RCBO, or an RCD and MCB of the correct type and rating.

It's a bit blurry but the Contactum one would appear to say B40.

Need a 40A supply from the CU to feed the Bed, was just going to put a 40amp double pole RCBO just above the CU, then feed the 6mm2 cable direct into the Bed ! .
