400 amp ground wire size
Jul 21, 2023 · The terminology is grounding electrode conductor for the conductor going to the rods. Normally a 400 amp service would need 1/0 or possible #2 copper for the grounding electrode conductor but the code states there is no reason to be larger than #6 to the rods, as Jim posted. I think the reason is that an 8' rod in the soil will do no better ...Size of wires, grounding wire, conduit for wires all depends (firstly) on what the breaker supplying the power will be rated at. You've now commented that this will be 200A. With (typical, likely) 75 °C rated terminals at both ends this sets a minimum size of 250 kcmils for aluminum wire with an insulation rating of 75 °C or more.40 Amp Wire Size: 40A Wire Gauge For 220, 240 Volt Circuit (+ NEC Code) If you’re setting up a 40 amp circuit, you need to figure out what size wire you need for 40 amps. In particular, you have to choose the right AWG gauge wire to handle that current. With a 40 amp 240 volt circuit, you will have a circuit that can handle 9,600W wattage.

Electrician said 4/0 aluminum 3-wire for the 200 amp service. Electrician said #2 aluminum 4-wire for 100 amp service to the garage.The grounding electrode conductor must be run either to both disconnects or to the meter. In NC we run it to the meter. Also if you look at the notes to 250.66 you would only need #2 copper to the water pipes not 1/0. Also with 4/0 aluminum your calculated load must be 360 amps or less.Also keep in mind requirements in 240.4(B) for over 800 amps - you can not use next size higher overcurrent protection so commonly seen use of 500 copper which has ampacity of 380 can be protected at 400, the next size device. But for over 800 amps you can't run three parallel sets of 500 as they only have a combined ampacity of 1140 amps.
18-, 16-, or 14-gauge wires for speakers. 16-, 14-, or 12-gauge wires for subwoofers. As with the power wire, the longer the run and the more current you're pushing through it, the larger size you should use. For example, if your amp is in the trunk and you're sending 100 watts to your front speakers, 14-gauge speaker wire is a good call.Screenshot of Table 250.66 for aluminum ground wire sizes.
