bank of flourecents keep tripping mcb (LED LAMPS)

[jibspark]

Hi All,

ive got to start a bit of fault finding in the next few days and thought i would get a head start...

I have a load of flourecent type fittings that use LED lamps all on one circuit, when ever the switch is turned off it trips the breaker, but not when the switch is turned on.

my first thought was just to much of an inductive load on one circuit, however im starting to doubt myself as they are LED lamps and not normal flourecents.

any ideas?

does anyone know much about LED light fittings?
