Wiring for Lighting 7

[shlim]

Hi there,

I have a case where a small fire had occurred at a wall switch for lightings in one office space. My electrician suspected too much loads routed to one single wall switch, up to 12 fluorescent lights (28Watt each), and that the norm is maximum 10 lights per switch.

Please share some lights if there is such a guideline or recommended practise? Have not come across any reference in the 17th Wiring Regulation or the Internet.

Thank you.

There's a paper speaking directly to this problem published by Electrofed in 2013. Google brings it up instantly under "Electronic Ballast Inrush current".

I don't typically work at the circuit board/design level, but I suspect that it wouldn't be particularly difficult or expensive to correct or reduce this however, and has become the norm here in the US?

No, it's not that hard. But it costs money.
