Who's responsible for changing RCD on distributors board?

Anonymous user 09/03/2024 - 2.48 PM

We have an old fuse board set up, with the fuse board only on our board, and the RCD and meter on the distributors board. The RCD is constantly tripping since we had a new boiler installed (0.03 when it needs updating to 0.3). Electrician said he can't do it as it would mean cutting off the tags which is illegal and it's the energy suppliers who need to replace it. Energy supplier are kicking up a fuss and saying if we had a qualified electrician (which obviously he was!) then he would know it's not their problem. It's been 3 weeks and I'm fed up of going back and forth with them and need it fixing!

Are you a tradesperson and able to answer this question?

This issue is approached in 2 different ways. 1/your electrician can request permission to remove the service fuse at the cut out, replace the RCD, replace the fuse and the DNO will come out later to reseal. 2/You can request a call out by the DNO to remove the cut out fuse and fit an isolator so your electrician can isolate, carry out his work and re-energise. (this would be the favoured option) Given the description of your current DB it may be time to consider replacement to a current regs compliant DB. As it would appear you may have issues with your current system and these issues would require repair or replacement, this may be the right time to upgrade. If you decide to do this, you do need to be sure you are using a registered electrician.

The electricity board are correct their responsibility ends at the main fuse and your electrician should know that, then the electricity charging company take responsibility for the meter. All the bits after the meter are for the customer to deal with. The RCD does need to be 30 mA or 0.03 not 300 mA 0.3. If the new boiler is constantly tripping the RCD then you might want to get the heating system tested and the fault found as any size RCD will continue to trip, I'm going to guess that someone has connected an earth in with a neutral somewhere or you have an existing failing component
