The whirlpool (spa) bath we've ordered comes with a European style fitted mains plug (yes, I know...) and an in-cable breaker of some kind - presumably an RCD - quite close to the plug. This obviously isn't a satisfactory arrangement for the UK, so will it be OK to cut off both the plug and the breaker and wire directly (via a double-pole isolator) - assuming that it will be connected to a circuit that already has a 30 mA RCD?
I've looked at earlier posts on this subject but they're all quite old, and don't cover the case of an in-cable RCD already being fitted.
