    Led tubes help

    Took down a 6 ft light fitting and replaced it with a 5ft LED twin fitting, I had to change the MCB from a 6a to a 10a MCB because the 6a keeps tripping off, Is there a big start up current on LED tubes?

    Protection by MCB or RCD/BO

    Am I correct with my interpretation of a/c protective device need not necessarily be RCD or RCBO depending upon install methods of cabling to inverter isolator and also dependant upon the inverter type. Protection by a type B MCB is ok. Sorry if this been mentioned before.Steve.
