2 1 xhhw 2 wire for 100 amp sub panel. Is the wire size to my sub panel too small. The calculator allows entry of a voltage drop but caution should be used when doing so to make sure you are calculating the wire sizes in accordance with nec article 210 19 fpn no.

3 2 2 2 ramapo triplex underground secondary distribution cable for 100 amp sub panel. Steve purchased our 6 awg thhn thwn copper building wire for his project. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. Multi conductor 2 gauge aluminum wire.

The national electrical code nec recommends a maximum voltage drop of 3 percent for individual household circuits known as branch circuits this is a good goal to shoot for when sizing the conductors for an underground cable the following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size awg and. 4 the nec allows a maximum of a 3 voltage drop on the main branch of a circuit at the farthest outlet of power and 5 total to both feeders and branch. From this sub panel i am feeding 2 20 amp circuits with 14 wire. Rated for direct burial no need for conduit.
