[QUOTE="Joeski1953, post: 545584, member: 36901"] No mate, the old board had MCBS, but was plastic, doesn't meet letting standards, changed to 8 way RCBO and SPD. All circuits work its the landing light that trips the RCBO, its a large led type with long leds (4 of them) Im hearing borrowed neutrals but why? they are 2 separate circuits one up one down.
