Copper wire for 600-amp service: In this case, we always need to follow a rule of thumb.The breaker size for the 125 AMP panels is defined based on the panel's highest current ability. The panel breaker size is not larger than its highest rating. For 120 AMP panels, there is the use of a 60 amp DOUBLE pole breaker. 14/3 copper feeder needs a 15A breaker. 12/3 copper requires a 20A breaker.He is requiring the 4oo amp service to have a 400 amp main panel, from there 2 200 amp sub panels. According to load, 500 cmils for service entrance is required. Meter is on the other side of wall. Service coming into the back of the panel. With double lugs on the meter load terminals, two 200a mains would also work.The amperage rating of the box does not matter at all. For example, the box is 500 amps and the biggest wire is 100 amps. Then having a 500 amp rated ground is pointless because the 100 amp wire will melt long before the ground will. The best ground is an 8-foot copper rod you drive into the ground with a sledge hammer.The wire is sized for the load. The fuses protect the wire. The fuses then are based on the load, not the disconnect. If you put 400A fuses in there, the conductors would have to be rated for at least 400A (unless feeding a motor starter). The size of the disconnect is only relevant in that it has to be 115% LARGER than the load.In this case, instead of using a 2/0 copper wire, you should use 300 kcmil copper with only a 2.78% voltage drop. This suggested size wire for a 200 amp panel will work for both single-phase and three-phase installations. On the other hand, if you are tight on budget, you can use 500 kcmil aluminum.0 (1/0) AWG Aluminum Ground Wire: 255 Amps: 350 kcmil Aluminum Wire: 0 (1/0) AWG Aluminum Ground Wire: 280 Amps: 400 kcmil Aluminum Wire: 000 (3/0) AWG Aluminum Ground Wire: 305 Amps: 500 kcmil Aluminum Wire: 000 (3/0) AWG Aluminum Ground Wire: 350 Amps: 600 kcmil Aluminum Wire: 000 (3/0) AWG Aluminum Ground Wire: 385 Amps: 700 kcmil Aluminum WireOur Video Guide for Welding Cable Size Chart. Wires come in multiple gauges; the smaller the gauge, the larger the cable. For example, if you have AWG 5 wire and use that wire for high power circuits, it helps to get as small of a gauge as possible. The AWG rating system is often misunderstood. For example, a size of 0 is not classified as 0/0 ...Ground cables should be the same size (or larger) as the power cable. ** Current Draw figures are based on RMS Power of the amplifier with a 50% efficiency rating. *** Although wire gauge sizes smaller than 10 gauge may be acceptable for the amount of current draw, we recommend using 10 gauge as the smallest wire size for any amplifier of 100 ...Title: SERVICE_ENTRANCE_CONDUCTOR_SIZES.pdf Author: boverton Created Date: 2/16/2016 10:40:49 AMAluminum MC Cable has a compact strand 8000 series aluminum alloy conductors.
