Amperage guide
Amperage tells you how much current a load draws. It is the starting point for wire sizing and voltage drop checks.
Power to current
Use the supply voltage to convert watts or kilowatts into amps.
Circuit size
The current helps you compare the load against the cable and breaker rating.
Voltage drop
Once you know amps, you can check whether the cable run drops too much voltage.
