Two wires on one breaker?

[Don1357]

The microwave outlet (compact, about 10 amps) and the extractor fan (minimal power draw) are on separate breakers at the box. Is it kosher to put two circuits on a breaker so I can free a slot? I don't imagine the microwave/extractor fan would ever get close to 15 amps draw.

Only if the two circuits are on the same sized cable. Ex. 14 gauge 15 amp breaker or 12 gauge wire on 20 amp breaker.

They are both 15 amp.

They are both 15 amp.

Better solution is to pigtail them in the box to a 3rd short wire, then attach it under the breaker screw. Coming up I was always taught to never have 2 wires under 1 screw. In instances like this, just watch your total load- you're safe on that account.

Some breaker terminals are rated for up to 2 wires. Others are not.

Just get a tandem breaker. Something like this

CH 2-20 Amp 1-Pole Tandem Circuit Breaker

It depends on what breakers you have, some are rated for two wires others are not. If not:

-You can do a pigtail in the panel.
-You can use a half height/tandem breaker to get two circuits in the space of one.
-If the microwave outlet and extractor fan are near each other you can also just feed (fish) one from the other in the kitchen and disconnect/abandon the other line.

should be fine however breaker lug may not be rated for 2 wires. wire it with the pigtail method as said above

OPs panel may or may not be rated for twins.

Eaton is making twins for panelboards made for BAB (bolt-on) breakers too.

interesting but we dont know what brand of panel the OP has...

True, but since the CHT breaker was displayed........

Haha. I just picked the first one that came up to show the style...

I have no idea which box he has

Depends on what brand/model of breaker.
You can tie the 2 wires together before the breaker then run a single wire to feed both though.
