Low Voltage Devices - Branch Circuit Device Count


Located in Calgary AB Canada

Apologies if this is in the forum already.... Quick question about the impact of low voltage lighting on device circuit count. Don't want to make an assumption..

Local code states that no more than 12 devices may be placed on a 15 Amp circuit. I am wondering if a set of 6 low voltage lights with 1 transformer counts as 6 devices or 1 for the purposes of devices on the circuit?

I would be checking the amp draw of the single transformer to make sure it doesn't negatively impact the rest of the circuit.

Welcome to the forums.

The low voltage transformer for that lighting system counts as one device.

Normally you just count switches or receptacles. The low voltage system just plugs in.... it's not considered a permanent addition.

Based on the amount of low voltage lighting you have connected.... those transformers usually only draw an amp or two.... maybe three tops.
