Any ideas on this one?
Two kitchen lights, both with circular fluorescent lamps and wired to come on together, keep tripping the RCD when the lights are turned off. This seems to me to be a symptom specific to fluorescent fittings with coils.
The room is switched with two 2way switches and an intermediate. They are all 10AX switches. The RCD trip time is normal and doesn't trip at 15mS.
Would I be right in thinking that the RCD (not an RCBO by the way) is tripping due to the surge on the collapsing coil? Is this likely to be a fault with the light fittings?
Yes, they are customer-supplied and from Homebase
