116 ft 12 gauge 15 amp circuit voltage drop
Wanting to run 116 ft 12 g on 15 amp circuit. This is for a dedicated heated floor that draws 4.8 amps which is on a thermostat. This is the max draw being its dedicated. Will the voltage drop effect the usage of the heated floor?

The short answer is no. At 116 feet even with 14 ga wire, the voltage drop is 2.49% at 4.8 amps of current. So, you will be just fine with #12 wire. The typical recommendation is to keep voltage drop to no greater than 3%.

Thank you for the quick response!!!
Should I save some money and go with 14 gauge? I was going with 12 because of the length..

Voltage-120, 4.0 amps, 475 watts with a resistance of 32.3 ohms. It’s a schluter ditra heat.
Thank you !!
Thank you !!

You may get a slightly higher voltage drop that would equate to a lower wattage output but will still be fine.

Thanks for all your help! I ended up running 104 ft 12 g on a 20 amp circuit. Went with the 12 g because it was only $15 more. Thanks again.
