Why does Tesla recommend such a small gauge wire for their …
2020年6月18日 · According to this chart, 6 gauge wire would only be sufficient out to 15 ft for 50 amps (or 50 ft if we allow for 10% voltage drop); neither of which is close to the 150 feet suggested by Tesla. Given the clash between my internet-educated understanding, and Tesla's official publications probably written by electrical engineers, I have a ...
electrical - What size breaker and wire do I need for central air ...
Most likely you need 8-3 with ground thnn or thwn with 50 amp disconnect mounted within several feet from unit with a 50 amp circuit breaker in the main distribution panel. This is good for 50 amp rated unit. Use 10 awg for 30 amp unit or 6 awg for 60 amp unit. These rating are adequate for runs of up to appx 60 ft
How do I properly size the ground wire for a subpanel?
2020年10月12日 · Your 1AWG Al is good for a 100 AMP feeder (actually 110). From NEC 250.122 this requires an #8 CU or #6 Al ground wire as a minimum (or 6CU and 4 Al if you are really running a 110Amp Feeder). As a reminder, your feeder will be 4 wires, the two hots and the neutral will be #1AL (unless you've de-rated the neutral to 70% or from specific load ...
electrical - What wire do I need for a 48A EV charger? - Home ...
2023年9月14日 · Wire ampacity ratings are for the breaker, not the de-rated load size. 6AWG copper NM may not be used for a 60A circuit / 48A continuous load. For that load, you need 4AWG copper NM, 6AWG copper THWN, or 4AWG aluminum THWN. That’s all assuming you really need 48A charging.
What size wire do I need for a 100amp underground 300 ft run?
So if not really needing full 100 amp load, can go down smaller wires sizes, but use smaller breaker to meet the maximum amperage rating for that wire. so for example could use a popular 2-2-2-4 URD Aluminum direct burial wire, but would only use a 60 amp breaker for that distance, 80 amp if needed but could experience some voltage drop at high ...
What Wire Size for 100amp Subpanel - Home Improvement Stack …
2023年2月23日 · With that said, the NEC 120% rule seems to apply here and considering I'm almost at 100ft, it looks like the wire needs to be rated for 120AMPs. Based on the ampacity charts I've found, I'll need 1AWG (rated for 130amps) wire for this. Bottom line, cost is not too different so I really just want to do the best possible job on this project.
Conduit Size for Sub-Panel run? - Home Improvement Stack …
2016年4月18日 · You can fit 3 in a 3/4" but you need to pull a ground wire too so you will have to upsize to 1". With the distance to your sub-panel it would be advisable to upsize your wire one size further. So, #6 for a 50 amp #4 for the 60 amp. This would necessitate a corresponding increase in pipe size to 1" and 1 1/4" respectively,
What wire AWG for EV charger? - Home Improvement Stack …
2023年11月18日 · Being over 60A, your charge station requires a disconnect switch. I don't make the rules, but this will save its cost on wire, because a disconnect is a cheap way to splice from aluminum to copper wire. The textbook answer is #1 aluminum from panel to disconnect, and #3 copper from disconnect to EVSE. ("charger"). Source: Table 310.15(B)(16).
underground - Running a 50amp 240V line 300 feet to a shed
2020年6月15日 · First, you must determine the absolute minimum wire size, even if the cable were only 1 foot long. You either. start with your actual load and multiply by 125%, so for instance if you have a 39A hot tub, you must multiply by 125% to get 48.75A, which rounds up to 50A. Or
Wire size to run 200' to a shed - Home Improvement Stack Exchange
2021年4月20日 · The wire size all depends upon the maximum load and distance. in your case #6 ga copper would provide you with about 50-55 amps, depending upon temp derating. Are you planning on a 240v sub-panel? If so, that would require 2 hots, a neutral and a ground.
