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

    I have just installed two 250W 24 power supplies for LED tape. I have put them both onto one C6 and am crossing my fingers as when I read the spec it was 70A inrush each. According to the Hagar tech specs for fluorescent lights I need a C20 or B32 to cope with 140A of inrush.
