I am buying a dry sauna that has a 20-amp plug. The outlet in my home says 15A. The breaker for this outlet says 20. Can I use this dry sauna on this outlet. Do I need to change the outlet. Is breaker adequate if I do this? Dry sauna brochure says: 120 volt / 1531 watt/ 12.75 amp. If I change anything, is it possible I need a permit from the city? Thanks.

I suggest that you place the Sauna on an dedicated 20 amp circuit.

This means that the breaker needs to be a 20 amp breaker. The cable from the breaker to the outlet receptacle must be 12/2 AWG for copper.

The receptacle should be a 20 amp receptacle.

As to the permit, a simple phone call to the LAHJ (electrical inspectors) can get you that answer.

One major concern that I have is that someone may have installed a 20 amp breaker where a 15 amp breaker had been installed. If that happened and the cable was not upgraded to 12/2 AWG then you may well have a fire hazard inside your wall.

A 14/2 AWG cable is not allowed to be used on a 20 amp circuit.
