| Mar 20, 2022 at 0:18 | comment | added | Harper - Reinstate Monica | @ThreePhaseEel They made it a table again? cringe NEC 2014 had it right, making it a percentage. That stopped people from mis-using it for smaller-than-service feeders. | |
| Mar 19, 2022 at 23:13 | comment | added | ThreePhaseEel | @Harper-ReinstateMonica -- yeah, 500kcmil Al is one size too small for a 400A feed to a dwelling unit (Table 310.12 gives it as good for 350A) | |
| Mar 19, 2022 at 20:14 | comment | added | Harper - Reinstate Monica | @ThreePhaseEel Good point, I missed that detail. Forget ranch panels unless OP wants distribution at the pole and 200A to the house. OR, the AHJ knows something we do not; given OP's circumstances (no reason to have it there except the power company refuses to extend) perhaps the AHJ intends a waiver. I'm really, really wondering where the choice of meter and wire came from, especially as 500 kcmil aluminum is 310A (so a little light for 400A). When something is that oddly specific, I tend to assume hidden wisdom. | |

| Mar 19, 2022 at 19:44 | comment | added | ThreePhaseEel | @Harper-ReinstateMonica -- for ex: the equipment package I propose in my answer uses a $2300-$2500 meter-main (as of the time of this writing, there are a couple authorized Siemens distributors that show that cheap on Octopart) and a $1k switch (HD's list price), with about $500 at most in auxiliary parts (lug kit, neutral block, grounding block) | |
| Mar 19, 2022 at 19:42 | comment | added | ThreePhaseEel | @Harper-ReinstateMonica -- problem with trying to jumper the meter on a ranch panel at the house is that ranch panels (like all the other meter-mains out there) have a permanent factory N-G bond (i.e. they're labeled as suitable only for use as service equipment). 400A equipment is still somewhat costlier than 2x200A, but the prices also vary wildly depending on whose equipment it is and where you're sourcing it from | |
| Mar 19, 2022 at 19:31 | comment | added | Harper - Reinstate Monica | @ThreePhaseEel OP may be getting that impression from me. Last time I priced 400A main breakers they were over the moon. If the industry has made huge progress in getting prices down I'd be glad to hear it. I was under the impression that AHJs were granting exceptions to help consumers with the costs, e.g. turning a blind eye to the "single 400A breaker" requirement and still allowing dual 200s. I agree the ranch panel may not be usable at the pole, but possibly at the house (meter bypassed). | |
| Mar 19, 2022 at 17:48 | comment | added | ThreePhaseEel | @Cstreight -- also: what prices are you seeing for 400A disconnect hardware? I'm trying to get a sense for what you're calling "astronomically expensive" compared to the numbers I've seen online for hardware in that class | |
| Mar 19, 2022 at 17:46 | comment | added | ThreePhaseEel | @Cstreight -- can't do the latter as that violates NEC 225.30, which prohibits 2 feeders to a building unless you fit into its list of specific exceptions | |
| Mar 19, 2022 at 12:43 | comment | added | C streight | So seeing as how i already pulled the 200+ ft of 500/500/350 the only option is a 400Amp disconnect that is astronomically expensive or removing the wire i pulled previously and installing my 2/200amp disconnects at the meter and re pulling parallel feeders to my 2/200amp panels at the house...correct? | |
