Consumer unit upgrades

Fuse Board Upgrades, Dublin

Old fuse boards were built for a house with a kettle and a telly. If yours still has fuse wire in it, it is protecting a modern home with equipment from another era.

Signs your board is past it

Any one of these is worth having looked at. A smell of burning is worth ringing about today, not next week.

  • Fuse wire or old cartridge fuses rather than switches you can flick back on
  • No RCD, so nothing cuts the power fast enough to stop a shock
  • A board that trips again and again and nobody has explained why
  • Scorch marks, discolouration, or a smell of burning near the board
  • A board so full there is no room to add a circuit for a shower or a charger
  • A board that has been added to over the years by different people

What an RCD actually does

A fuse protects the cable. It blows when too much current flows, which stops a wire overheating inside a wall. That is worth having, and it is all an old board does.

An RCD protects the person. It watches for current leaking to earth, which is what happens when somebody touches a live part or cuts through a cable in the garden, and it cuts the power in well under a tenth of a second. A fuse will not save you from that. An RCD will.

That is the real difference between a fuse board and a modern consumer unit, and it is why a board with no RCD is the thing we most often recommend dealing with first.

What the work includes

  • The existing circuits tested before anything is swapped
  • A modern consumer unit with MCBs and RCD protection
  • Every circuit labelled properly, so the next person can read it
  • Certification, notified as a Safe Electric Registered Electrical Contractor
  • Any small faults found on the day put right there and then

A new board on bad cable is money wasted

This is the part people are not usually told. A modern board is better at detecting faults than the one it replaces, so if the cable behind it is failing, the new board does its job and keeps tripping. The board is not faulty. It has found something that was always there.

So we test before we swap. If the circuits are sound, a board upgrade is the right answer and we will say so. If they are not, you will see the evidence rather than take our word for it. The Full Electrical Survey and Report is €700 for a standard house and tells you which of the two you are dealing with.

Send us a photo of your board

Easiest thing you can do. One photo of the inside of the board tells us most of what we need to know, and you get a straight answer without anyone calling out.
