What Gauge Wire To Use?

[ricklev]

I'm replacing some ceiling fixtures. What gauge wire should I buy? The new fixtures use a single 100 watt incandescent bulb.

Do they sell the screw type wire connectors here? I've never seen them.

Thanks for your help!

[IMHO]

For lighting circuits, 1.5mm2 THW.

1.5 mm² THW in conduit, VAF if running naked (watch for wildlife chowing down on it).

Protect with a 10A breaker.

Choc-bloc and wire-nut type connectors are readily available.

Thank you!
