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.
