The Correct Wire Sizes for a 50A Sub Panel. According to the size chart recommendations from the 2002 edition of the NEC, the minimum wire for 50 amps should be 6 AWG for copper. For aluminum, it should at least be 4 AWG. However, these answers assume that there’s no voltage drop to consider. The NEC considers a 5% voltage drop as the maximum ...For the full 100A, use #1 aluminum. You may have heard negative things about aluminum (you're not getting the whole story)... but aluminum feeder of this large size is perfectly fine and there has never been a problem with it. Besides, the panel lugs are aluminum lol, as are the buses on most panels. Re-examine the requirement for 100A.Sep 25, 2022 · 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 circuit voltage. As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 ... 100A sub panel wire size. I had a subpanel installed and it failed for several things one item is that the electriction ran 3c 2awg alumin wire and the inspeactor says that is not good for 100A. The electrition came back and had to run a new wire and he is insisting the 2awg alumin wire is fine for 100Amps. Where can I look this up, my subpanel ...Heating Sources For Your Workshop.
