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 ...The wire gauge for a 100 ampere subpanel is #2 AWG for aluminum wires. But this answer may change if the length of your cable is too long. It may also depend on the load you choose to put on the wires. This article will explain what size aluminum wire is necessary for a 100-amp sub panel, so you can make an informed decision.Wire Size For 60-Amp Subpanel 50, 100, or 150 Feet Away. 50-foot distance: 4 or 6 AWG will be good for Aluminium or copper wire material. 100-foot distance: 2 or 4 AWG is best. for Aluminium or copper wire. 150-foot distance: for this distance use aluminum wire of 1/0 AWG or 2 AWG gauge.3370 posts · Joined 2008. #3 · Jun 16, 2011. I doubt you will be able to find romex large enough to handle 100 amps. #2 is listed in Southwire's catalog, with a 95 Amp rating.

The 60A breaker feeding the 6/3 (I hope it's copper) will limit the current to the subpanel to 60A per 120v leg. The panel must be rated for a minimum of the size of the breaker feeding it. You can put as many breakers in the panel as the panel will hold, you just can't concurrently use loads that will exceed 60A per 120v leg.Re: three phase sub panel wire sizing Bryan, this is a real question. Why would I not simply choose conductors rated 200 amps or more and forget about the calculations? Assuming this sub panel is protected by 200 amp OCP the smallest conductor allowed regardless of calculations will be 3/0 and the largest required conductor would be 3/0. Edit ...lets assume, you are using copper wire, 110v LN, ac single phase, single set of conductor and need to have voltage loss of 4% to load, assuming you are directly connected to the main branch, 2 awg for both line neutral are correct. Neutral and hot should be the same - whatever is going out, must be coming back!When it comes to wiring a subpanel, the size of the ground wire is an important factor.

I'll need 70-80 feet of wire to run from the main panel to the new sub-panel. Picture of current main panel attached. Sub-panel breakers:
Inside the main panel will be a breaker which feeds the wiring to the subpanel. The lesser of those current ratings decides the size this breaker must be. Example: you have a 200A subpanel connected via 6 AWG feeder. This must be fed by a 60A breaker in the main panel. The wire size is the limiting factor.In this case, a 100 amp sub panel would require a minimum of 4 AWG copper or 2 AWG aluminum ground wire. However, it’s important to also consider the …
If you need a 100-amp subpanel, you'll be running beefy 3- or 4-gauge cable with a 6-gauge ground wire. What size wire should I use to feed a subpanel in my garage?

Run the wire from the main panel to the sub-panel box.@Roko100 Since it's a subpanel, and outside not in the building, yes, you'll need both the ground wire and the grounding rod there. If it was inside the same building you'd only need the ground wire. Also since you only want 120V, the 3 wires will suffice. It will be a 120V subpanel. -The National Electric Code (NEC) requires "Distance from the subpanel due to voltage drop (NEC 310-16 Code)," and by using the factor you will find that a 100-amp service requires a maximum of #3 AWG ground wire. A wire with a diameter of 3 AWG can handle 100 amps. The NEC code specifies the distance between a sub-panel and the wiring.For a 50-amp sub-panel, use #8 THHN wire; for a 100-amp sub-panel, use #2 THHN wire. Connect the main panel to the sub-panel box with the cable. Run black, red, white, and green wires from the sub-panel box to the main panel box. Keep the copper wire inside if the temperature is cold outdoors to keep it warm.Runs don't look excessive, so 12Ga for 20A and 14 Ga for 15A should be fine for wire sizes. For a 70A breaker, #4 Cu. For 80A, #2 Al. For 100A, either #3 Cu or #1 Al. (It may be weird to get 30 extra amps for a 1-unit size bump, but remember - we can use the 75C column at 100A).Generally, for a 100 amp sub panel, you'll need a grounding conductor that is at least #8 AWG copper or #6 AWG aluminum. First and foremost, you'll need to check the local electrical code requirements. When it comes to determining the ground size for a 100 amp sub panel, there are a few factors to consider.

A brief visit to the code indicates that there is a bigger problem, in that the ampacity of 8Ga copper is only 55 at 90C (aluminum 45 Amps) so your wire is too small for a 100 amp service. You need a bare minimum (if everything is rated for 90C) of 3Ga copper or 2Ga aluminum, and probably larger after various derating factors are applied, or if 75C is the limit on any connection.Wire Size For 100 Amp Sub Panel 150 Feet Away. Alright, as we have calculated before, we need at least 125 ampacity wire to handle 100 amp current. Now we need to add the 30% amp boost (+20% per every 100 feet, hence +30% for 150 feet) to these 125 amps: Min. Wire Ampacity (150 ft away) = 125A × 1.3 = 162.5 Amps.At that point you will go 4-wire, and since the new extension is 4-wire, you are Code complete. Save money other ways. The current subpanel has the same breaker size as the intended feed to the sub-subpanel. As such, the $40 subpanel breaker feeding the sub-sub is redundant. Get rid of it.
