unless of course its enclosed by an earthed metallic sheath, installed on the surface, for a single designated piece of equipment or buried to a depth of more than 50mm
er not quite if it is a socket circuit of less than 32 amps rcd protection is still required
Back to the OP yes if the circuits are not changed in any way yes there is nothing wrong with your consumer unit
But sorry you must be a bit daft not to get RCD protection for your house, Your consumer unit was fitted in the days of a Austin Allegro bet your car has anti lock brakes and airbags. How much time do you spend in a car????
The consumer unit you have is the same as in a house I had to test the day after a toddler was killed 15 years ago, I never never want to do a job like that again I cried afterwards . Would a RCD of saved the poor kids life most probably.
Sorry but your choice
