Wire Size

Hi all.
I have a 1000w appliance run on 220 voltage? I use the following to make it running.

A 15 amp breaker.
A commercial type outlet receptacle.
12 Gauge wire (normally for heating)

How many feet should I allow to run. because from the main pannel to the gargage was kind of far.

Thanks in advance to your input.

You won't have a problem running that circuit 150 feet, probably even more.

It depends on what this "appliance" is. If this unspecified appliance has a motor, it cannot stand as much voltage drop as if it does not.

Normal designs allow for 3% to 5% voltage drop. 1000 watts on 240 volts uses 4.2 amps. 4.2 amps can go 850 feet (each way) over 12-gauge wire before losing 5% of 240 volts. It can go 500 feet before losing 5%.
