I bought a treadmill and every time I try to operate it, it trips the circuit breaker. It's a new community,and it's not a gfci outlet. I do have it plugged into a surge protector.

Most treadmills I have seen need a dedicated 20A circuit. It is probably on a circuit with other loads.

What does "It's a new community" mean?

You said it was not GFI, but is it an AFCI circuit?

Suggest you review this post.

It means my house was just built a little over a year ago.

It is an AFCI circuit, yes.

Yes it is an AFCI circuit.

Yes it is an AFCI circuit.There is more likely your answer.
AFCI's don't play well with things like treadmill motors.

As Stan pointed out, treadmills likely require a dedicated 20 ampere circuit...
If this is a circuit with multiple outlets or a 15 ampere circuit breaker you may need to change it to a 20 ampere...
There should be a "plate" on the treadmill with the Voltage, Phase, Amperage or Wattage on it... what does it say? This info would be helpful.

For some reason, treadmills do not work well with AFCI breakers, and I have seen other solve the problem using a good quality surge protector.

Stacy may need to find a better surge protector.
