We record each outgoing cable run and its function so every circuit returns to the correct breaker rating. ### Mounting and terminating the new enclosure The old fuse box is removed from the wall and the new metal board is secured in position. New meter tails are brought in, protective bonding is connected, and each circuit is landed onto individual miniature circuit breakers and residual current devices. ### Full testing and circuit labelling Each circuit undergoes dead and live testing to check continuity, insulation resistance and trip times. Power is restored, clear printed labels are applied to identify every switch, and the installation is verified operational. ## Frequently asked questions about fuse board replacements ### How long will the electricity be turned off during the swap? Power must be isolated while the old board is removed and the new consumer unit is mounted and wired. For standard domestic installations, the supply is typically off for a few hours. We re-energise circuits as soon as testing permits. ### What is the difference between a traditional fuse box and a modern consumer unit? Old fuse boxes rely on pieces of wire or basic cartridges that melt when overloaded, offering limited protection against electric shocks. Modern consumer units use miniature circuit breakers that flip instantly and residual current devices that detect tiny earth leakages to prevent electrocution. ### Can the new consumer unit fit in my existing meter cupboard? In most homes, the new metal consumer unit fits directly into the existing space. However, modern enclosures are built to current non-combustible standards and may have slightly different dimensions than vintage fuse boxes. We check the cupboard layout beforehand to confirm adequate clearance. ### Do I need a new board if my electrical inspection has failed? If an Electrical Installation Condition Report flags missing residual current protection, an obsolete enclosure or inadequate isolation facilities, upgrading to a modern consumer unit is usually the recommended remediation step to bring the installation up to standard. ### Will you need to rewire my entire home when replacing the fuse board? No. Replacing a consumer unit connects your existing wiring onto new protective devices. We test the existing cables to ensure they are safe to connect. Only individual circuits showing severe degradation or insulation failure would require wiring repairs. ## Other services in Parkstone - [Electrician in Parkstone](https://mx2-electrical-ltd.co.uk/electrician-parkstone): Electrical inspections, repairs and planned installation work across Parkstone, Ashley Cross, BH12 and BH14 from MX2 Electrical. - [Consumer unit replacement (all areas)](https://mx2-electrical-ltd.co.uk/services/fuse-board-replacement): MX2 Electrical replaces fuse boards and consumer units around Poole and Bournemouth.
