LED lamp startup currents and MCB/RCBO

psychicwarrior over 3 years ago

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 ?

Hagar have a section on the suggested surge capability of their MCBs on page 40 of their MCB catalog. It relates to fluorescents but the values should relate to any switch on surge. I do not know if there is anything more up to date.
