# Fuse Box Upgrades in Aldringham (IP16)

This page is for Aldringham, IP16.

Most people say fuse box. The trade says consumer unit, and replacing one is not a straight swap.

The work starts before the quote. We check the earthing arrangement, the size of the main earthing conductor and whether main protective bonding reaches the incoming gas and water. PME supplies need bonding of at least 10mm2, other arrangements at least 6mm2. We also take insulation resistance readings on every existing circuit. New RCDs pick up earth leakage that old rewireable fuses never saw, so a board fitted on top of a damp or degraded circuit will trip on day one.

Modern units are steel for a reason. Regulation 421.1.201 requires a non-combustible enclosure in domestic premises, brought in during January 2016 after fires involving plastic boards.

Then the real choice. On a split-load board several circuits share one RCD, so one fault takes out half the house. An **RCBO** gives every circuit its own combined RCD and MCB, so a fault on the kitchen ring leaves the lights on.

Replacing a consumer unit is notifiable under Part P and gets an Electrical Installation Certificate.
