An electrician in Ontario, Canada is unsure how to correctly determine the wattage for an air conditioner when performing a service load calculation, specifically whether to use the minimum circuit amps or nameplate ratings.

Existing resources (like CEC code books or online forums) lack clear, accessible guidance on converting air conditioner nameplate data (e.g., MCA, RLA) to wattage for service calculations, especially for Canadian code requirements.
