Circuit breaker in home office suddenly shuts down on me

Hello. We have a home based business and a breaker in one of our offices started shutting down whenever we run a space heater and try to print something at the same time. The office does have 3 computers in addition to a halogen lamp all on the same breaker. We havent had this problem since the beginning of the winter. I'm not sure if the breaker can simply be replaced or we need to upgrade further because of the load. Thanks for the help!

Welcome to the forums!

It sounds like the breaker is doing its job and protecting the circuit from an overload. Most electric space heaters draw a lot of power, and that's probably what's taking it beyond its limit.

I'm not sure if the breaker can simply be replaced or we need to upgrade further because of the load.
No gain from replacing a working breaker. To help us answer your second question, tell us what size the existing breaker is and whether there is more than one circuit feeding receptacles in your home office.

Is it a laser printer?

They also use a lot of power to fuse the toner onto the paper.

I too suspect the heater in the printer is kicking in on a circuit that is close to overload with just the heater running.

If that space heater is 1500 watts and it is a 15 amp circuit then just the heater draws 12.5 amps of you available amps. That leaves you just 2.5 amps for everything else in the room. But wait you have a halogen lamp. if it is 100 watts you now have only 1.67 amps left for every thing else in the room. I'd say it is reasonable and normal that the breaker was tripping. You need to install a dedicated circuit for the heater or find a better way to heat the office.
