Good afternoon everyone
Bit of a long read here! Trying to give as much info as I can. There is 2 sheds with power and I’d like to add power to a 3rd.
Wondering what would be the best practice for installing a new consumer unit in an shed (shed 3) coming from a 32A breaker in an existing consumer unit (shed 2)
To start at the beginning, the main supply for the original consumer unit in shed 2 comes from a 32A breaker in a type B MCB board connected to the fuses/meter in shed 1 via a 100A breaker.
From the consumer unit in shed 2 there is a 32A breaker spare which I would run a 6mm SWA cable to the consumer unit in shed 3.
My question is that since there is an 80A/30mA AC type RCD in the consumer unit in shed 2, and a 63A/30mA A type RCD in the new consumer unit in shed 3, would it be best to fit an S Type RCD on the consumer unit in shed 2 to give some discrimination so that a fault in shed 3 wouldn’t also trip the consumer unit in shed 2?
The new consumer unit will have a double socket fitted to the 16A breaker and a few strip lights to the 6A breaker.
Appreciate any advice.
