A friend asked me to look at his lights. The cheap dimmers had conked. He got a home repair man in who made it worse and walked away charging £110 for doing nothing.
The dimmers were already bought and ready to fit. I traced all wiring and fixed the dimmers eventually. The wiring was a disgrace with wires running to strange places with one hall light switch box being a sort of junction box. Well now sorted after much figuring out.
I noticed that the RCD was before the CU and main breaker in the CU. The CU is an old Wylex with plug in mcbs, about 25-30 years old. The mcbs are the sort that converts fuses. It is a flat. Outside the flat there is a distribution box with a cluster of main fuses for around 10 flats. To work on the RCD the main fuse would need pulling.
In ready made CUs with RCD inside they are all after the main breaker. Is is right to put an RCD before the CU and main breaker?
