- Issue - above calculator does not fix voltage
Procedure
- Select convenient length
- Select max temp - such as 550C = 1000F
- Match gauge to proper voltage drop of 120V
- Find out max gauge that is within current limits (15A) and has correct voltage
- Limit for 15A outlet is 1800W
Sample:
- Remains within 15 amps
- Shows correct voltage
- Max temp - select it to match voltage - you determine max possible temp and judge whether it will burn out your system if you have temperature sensitive components
- Note that Gauge 17 is the max fatness that stays within 1800W
- Note: 22' of 18 ga gets us right at 120V, and 1560W. Good. But temperature of 1260F is a little high.
Examples
- 12' of 26 ga draws 450 Watts.
- This was acceptable, but burns out thermistors if placed directly on heater.
