LED lamp startup currents and MCB/RCBO

psychicwarrior

Hello forum , good day to all

Accepting it can be a bit more involved science wise, but will any of you please share [if you use/have] a general/simple ‘formula’ or 'rule of thumb'  for working out how many LED lamps that a MCB/RCBO Type B or C of some rating is able to switch and not end up nuisance tripping on same-time startup  ?

 

Regards

Habs

    This was mentioned in a webinar yesterday … the answer seems to be that there is a huge amount of variation between designs (some are ‘soft-start’ and have little or no startup surge,  others are horrible and can only have a few on an MCB) - so it's really a matter of asking the manufacturer.
