What size wire do I need for a 400 amp service?
400 amp service requires a wire size of 1,000 kcmil.
What amperage is 750 mcm good for?
Table 310.15(B)(17)
| Size | Temperature Rating of Copper Conductor | |
|---|---|---|
| (AWG or kcmil) | 60°C (140°F) | 90°C (194°F) |
| 600 KCMIL | 575 | 780 |
| 700 KCMIL | 630 | 850 |
| 750 KCMIL | 655 | 885 |
What size wire do you need for a 800 amp service?
Conductors – 800 Amp The smallest conductor size for a 240 Volt – 800 amp service will range from #6 AWG for a short 20′ run to 600 MCM for an extended run of 500′ based upon a 3% voltage drop for a 1-Phase-3-Wire load circuit in PVC.
What size aluminum wire is good for 400 amps?
400 amp service requires an aluminum wire size of 1000 kcmil, whereas a copper 600 kcmil can handle that amount of power – take a look at the NEC electrical cable chart below.
How much is a 400 amp panel?
Factors That Impact The Cost to Replace an Electrical Panel
| Amperage | Estimate Cost |
|---|---|
| 125-Amps | $1,500 – $2,700 |
| 150-Amps | $1,800 – $3,000 |
| 200-Amps | $2,000 – $3,500 |
| 400-Amps | $3,000 – $4,500 |

THHN Stranded Building Wire….Product Details.
| Cable Type | THHN/THWN-2 |
|---|---|
| Wire Size | 600 MCM |
| # of Conductors | 1 Conductor |
| Conductor Material | Bare Copper |

Can I upgrade to 400 amp service?
Upgrading your home’s electrical panel from 200 to 400 amps is a smart and important thing to do for various reasons. Most importantly, hiring a licensed electrician to make this change will protect your home and family from potential danger.
Can you use 600al on 400 amp service?
Using 600AL on a service with single main 400 amp OCPD is noncompliant even using the “round up” rule as 350 amp OCPD’s are available. A person needs to select a conductor size with an ampacity past 350 amps to be able to select the next size up 400 amp OCPD assuming the calculated load is less than the conductor ampacity.
Can you use 500 mcm XHHW in a 400 amp service?
As long as the calculated load is less than 350 amps, yes. I am building a 400 amp (class 320) service. Is it permissible to use 500 MCM XHHW aluminum (350 amps rated) since the load is not constant on a service?
How big of a conductor do I need for 400 amps?
A person needs to select a conductor size with an ampacity past 350 amps to be able to select the next size up 400 amp OCPD assuming the calculated load is less than the conductor ampacity. FYI, I’m referencing 310.15 (B)16, 240.4 (B), and 240.6 (A). 600AL is 340 amp conductor.
