I have bought a Hagar CU 12 way split load RCD protection.I have also bought 25mm tails.I want to replace an old CU.A fully qualified electrition is going to do for me.Could he fit isolator or company has to do it.Is The isolator generally fitted between supply fuse and meter or between meter and CU.Can somebody give me some idea what sort of price are we looking for.
Thank you.
