My garage has a small consumer unit fitted with elcb and mcbs for the socket and lights. After cutting through a circular saw cable it did not take out the garage elcb but the elcb in the house consumer unit. If I get an electrician to changed the mcbs for Rcbos would this prevent the house elcb tripping should I be so daft to do this again. If you don’t think this is suitable what should I request to the electrician to be done.
