What happens on the day
A fuse board replacement in Derby begins with checks on the incoming supply, then moves through removal of the old unit, fitting the new consumer unit, reconnecting circuits and testing, in that order.
- Supply and earthing checkNothing is disconnected until the incoming supply and the main earth bonding have been checked. Earth bonding is the conductor that ties the installation to earth so a fault clears safely. Space around the meter and the old fuse board helps the work start straight away.
- Old fuse box removedThe mains supply is switched off and the old fuse box comes off the wall. A new metal consumer unit, the modern board that houses a protective device for every circuit, is fixed firmly in place and prepared to take the existing wiring.
- Circuits reconnectedEach circuit cable is tidied and terminated onto its own breaker or residual current device on the new board. The circuit chart on the unit is filled in so every circuit can be identified at a glance later on.
- Testing before power returnsEvery circuit is checked for earth continuity and insulation resistance, and the trip times of the residual current devices, the safety switches that cut power fast in a fault, are measured. Power is then restored and an electrical installation certificate is issued.
