Need to fit a 25amp isolator switch for my 3Kw hot tub question is do
you fit the isolator switch after the RCD Consumer Unit or to the
supply cable before going to the Consumer Unit ?

Can you give us some more information on your layout here?

Why can you not use the "RCD Consumer Unit" as an isolator?

Is it actually isolation you need or functional switching?

I'd guess it's in the installation instructions - and the 25 amp bit a
direct quote from the 'translation'.


Which raises the the possibility that this appliance might not even be for
230Vac...

CAUTION!!!!

3KW happens to be 25A at 120V...... Is this a USA appliance??????????
Please check the rating label!!!!!!

You're right to mention it, but hot tubs I've seen in the U.S. all
connect to the 220V supply. Normally 110v circuits are 15A or
sometimes 20A.. Larger appliances are run from 220v to keep the
current and gauge of wire reasonable.
