What breaker and wire size I need to use for a floor heating system?
Breaker and wire sizes are selected based on the total amperage of the heating system connected to a single thermostat. This information is on the heating product's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.
