* Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area - these are only guidelines that will apply to most installations. Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.
The above specifications are only guidelines. If your home is already equipped with a large number of electrical appliances, you may require a larger electrical service than the one recommended above. Please consult an electrician before placing an order.
