![]() ![]() ![]() This isn't a standard conductor size though, so we should use a 6AWG copper conductor (which has 13.30mm2 of area) or a 4AWG aluminum conductor for this ground wire. Designed to maximize installation efficiency and to provide additional convenience allowing for an. Bought the lug attachment separately on the bottom of ground terminal. Multiplying that by the 8.367mm2 area of an 8AWG copper conductor gives us about 10.55mm2 for the resulting wire. The square D 23 terminal ground bar kit worked perfect in my Square D 100 amp Panel. ![]() the 1AWG that is required to meet Code ampacity rules gives us a size ratio of 53.49mm2/42.41mm2 based on the NEC Chapter 9, Table 8 conductor sizes (we can do this math in mm2 since the conversion factors cancel out here) or about 1.26. BEST HEAVY-DUTY: Eaton CHSPT2ULTRA Surge Protection Device. Turn off the main power at the main breaker panel Install the sub panel in a convenient location, such as a utility room or garage. BEST MIDRANGE: Schneider Electric Square D HEPD80 Surge Protection. Does this mean I can use the 25 amp panel derate + the 25 amp of the 120 rule (125 ampx.2 25 amp) for a total of 50 AMP. Size proportionately, according to the circular mil area of theįor instance, using 1/0 aluminum wire for the hots and neutral in your example vs. BEST BANG FOR THE BUCK: Eaton CHSPT2SURGE SPD Type 2 Surge Protector. After some investigation turns out that I have a 125 amp panel that has already been de-rated to 100 amp main breaker. Grounding conductors, where installed, shall be increased in Increased in size from the minimum size that has sufficientĪmpacity for the intended installation, wire-type equipment When you start upsizing wires for voltage drop control, the size of the ground wire is governed by NEC 250.122(B): It’s the point where power from a utility company enters your home first from the meter. If you are using a four-wire direct burial cable, then just use the ground wire in the cable as it will be quite amply sized for the job it is doing if you are using PVC conduit, then bare 8AWG copper would be my choice to keep conduit fill down.and then upsize from there based on how much upsizing of the other wires you do Updated on ApThe heart of the electrical system of every home is the main circuit breaker box called the main electrical service panel. You are correct that for a 100A feeder, the associated ground wire needs to be an 8AWG copper or 6AWG aluminum wire. ![]()
