Can I easily replace my old basement lights?
 
Hey guys,

I want to replace my basement lights with can lights. The house is 35 years old, can I simply just swap out the lighting without worry of amps / volts?

Also what If I wanted to add a few extra? Can I just add another wire from the previous light to the new one?

Yes you can remove your old lighting and use that feed for your new pot lights. You can only put 12 lights on a 15 amp circuit

Your recesed will most likely call for 90 degree C rated insulation.If you have NM cable it must be NM-B.

The NEC does not have a 12 light limit on 15 amp circuits. The circuit is based on the maximum wattage of the bulb that could be installed, not what is actually installed.

Most light fixtures have a maximum rating,
lets say for now its 100w.
If you have 12 lights, thats 12 x 100 = 1200w.
Your circuit must be able to safely supply this.
Even thou you might only use 60w lamps.
Cause at a later stage someone could easily
replace the lamps with 100w not knowing any better.

Its known as idiot proving.

The post above mine stated a limit of 12 fixtures from the CEC. The US uses the NEC which does not have the same rule.

DMX explained sizing the circuit.
