Amperage & Circuit Size Calculator
Find a heating element's current draw and the minimum circuit size for a continuous load. Enter the element's wattage and voltage.
Current = W ÷ V. Continuous loads (running 3+ hours) are sized at 125% per electrical code, so minimum ampacity = 1.25 × current, rounded up to the next standard breaker. This is a guide only — always confirm wire gauge and breaker sizing with a licensed electrician and your local code.
Get the exact element — not just the math
These figures come straight from the numbers you enter. A replacement still has to match your original element's data tag: voltage, wattage, coil dimensions, and terminals. Send us your make and model, or a photo of the old element's tag, and we'll confirm the exact part and ship it across Canada.
⚠️ Working on the circuit itself? Confirm wire gauge and breaker sizing with a licensed electrician and your local code.
