[SML] Source 4 Power and LED Cabling

[sdwheaton]

Choosing a breaker with a trip curve that allows for a high inrush will also help prevent nuisance trips.

The 9 fixture after first or 10 total on a "chain" is a result of the
powercon devices and the ETC UL listing, no different than the fine
print on an extension cord that limits the load you are suppose to put
on it.

The inrush is significant.  Power a bunch on at once even if the
normal load is well within the capacity of the breaker or other
devices, it may trip when it sees several times that for a half cycle
or so.

I plan on 10 max, through powered or not, on a 20 amp circuit.   I'm
sure more would work, until it doesn't.  One circuit for every 15' or
less of batten/rail, for 100% LED.
