DB Box Repair and Upgrade
Old distribution board, a burning smell, or breakers that keep tripping as you add appliances? Request a quote for a DB box repair or upgrade.
Signs your DB box needs attention
- A burning smell or scorch marks around the board. Switch off and get it checked.
- Old fuses or an ELCB rather than modern breakers and an RCCB.
- Frequent trips after adding appliances: the board may not suit today's load.
- Renovation: adding circuits for a kitchen or air-conditioning often means upgrading the board.

DB Box Repair and Upgrade: Questions
How do I know if my DB box is too old?
Fuses instead of breakers, an ELCB rather than an RCCB, scorch marks or a burning smell are all signs to get it inspected.
Do I need a full rewire to upgrade the DB box?
Not always. Many upgrades replace the board and reorganise circuits without rewiring the whole home. The electrician advises after inspecting.
