Boat Shore Power Fault Finding in Lymington

Lymington sits within Hampshire, and lymington is one of the South Coast's premier sailing towns with world-class marinas. We serve Lymington Yacht Haven, Berthon Marina, and the town quay with qualified yacht electrical work. We've worked through it long enough to know what matters.

RCD & MCB Tripping for Lymington Boats

Working in Lymington routinely, shore power that keeps tripping out is often caused by earth leakage in onboard appliances or wiring.
