Amperage calculator

Verify that your installation is safe.

This calculator determines the total quantity of amps used by your transformers and lamps on one circuit. It indicates also the minimum breaker size required to use in order to avoid a current overload and to assure that your installation remains safe.

The 80% rule must be respected in order to avoid a circuit overload.

Moreover, this calculator takes into account the type of transformer used (electronic or magnetic). You will note that electronic transformers consume less amps than magnetic transformers. This permits to put more on the same circuit.

*Attention: Ensure that the wire gauge used will support your electrical requirements.
