100 Amp Wire Size Chart

100 Amp Wire Size Chart - That tells you that for 75 c wire in conduit (the wire may be rated 90 c, for various reasons 75 c is the one you usually need to work with for this), the choices are 3 awg copper or 1 awg aluminum or larger. Feeders such as this are almost always done using aluminum due to cost. It is required to be the same size. The maximum amperage of the wire can be found in nec table 310.16, subject to restrictions of nec 110.14. Your 1awg al is good for a 100 amp feeder (actually 110). The ground wire can be smaller in size.

It will be about 100 feet from sub to main. Don't understand the directions on what wire size to use. So if not really needing full 100 amp load, can go down smaller wires sizes, but use smaller breaker to meet the maximum amperage rating for that wire. The neutral wire is a current carrying conductor just as the hot wires are. I was going to use a #6 stranded wire for for ground and 3 #3 stranded wire.

100 Amp Wire Size Chart - From nec 250.122 this requires an #8 cu or #6 al ground wire as a minimum (or 6cu and 4 al if you are really running a 110amp feeder). I use southwire's wire size calculator. The sub panel is to hook up a 7.5 horse air compressor and a welder. This will give us the current carrying conductor size required for our feeder.

We'll then use the lowest value, or 60°c if any of the above are not labeled. The sub panel is to hook up a 7.5 horse air compressor and a welder. From nec 250.122 this requires an #8 cu or #6 al ground wire as a minimum (or 6cu and 4 al if you are really running a 110amp feeder). I am adding a 100 amp sub panel off the 100 amp main breaker. At that length aluminum feeder would be much cheaper, selective boxes for;

At that length aluminum feeder would be much cheaper, selective boxes for; It is required to be the same size. The neutral wire is a current carrying conductor just as the hot wires are. All the current to the load must flow back through the neutral wire to the source.

It will be about 100 feet from sub to main. Feeders such as this are almost always done using aluminum due to cost. Don't understand the directions on what wire size to use. Feet, single (phase), aluminum, direct burial/conduit/overhead, minimum conductor size, input 275 (for the length), input 240v for the voltage, max voltage drop leave at 3 (but we will play with this), current at end (since you don’t know guess at 80), input 1.

That tells you that for 75 c wire in conduit (the wire may be rated 90 c, for various reasons 75 c is the one you usually need to work with for this), the choices are 3 awg copper or 1 awg aluminum or larger. From nec 250.122 this requires an #8 cu or #6 al ground wire as a minimum (or 6cu and 4 al if you are really running a 110amp feeder). For a 240v circuit i don't even bother crunching the numbers for less than 150’. Your 1awg al is good for a 100 amp feeder (actually 110).
