hi, I bought a used Precor treadmill. I have a dedicated 20 amp outlet to plug it in, was wanting a surge protector for two reasons. Primarily, to protect the electronics, secondly I would like an on/off switch easily accessible. Currently, the on/off switch on the treadmill is underneath the motor so a little bit inconvenient. looking at surge protectors, majority of them are 15 Amps so I am unsure if that would be enough. Any input would be appreciated, thank you.
