That's a good point, and interesting to know that under torquing is a more common culprit of fire issues. I'm not sure all these guys use a torque wrench, though they're supposed to. For me, the concern is that without EMS, I could easily see 150A (64A EV charging + 50A duct heater + 40-50A hot...

It sure seems like it. Based on that, in the event of a fire due to the conductor being undersized, do you believe I'd be at risk for insurance coverage, even if the county has informed me that the existing conductor is sufficient? You're probably not a legal expert, but curious how you are...

It's a good point. Here is the scenario I presented: "Single family dwelling with 320A service. Meter enclosure (no disconnect) feeds two 200A main breaker panels. Load calculations show the 4/0 Al feeders between meter socket and the (2) 200A disconnects will see greater than 180A." So, I...

The county came back today with the below statement. Clearly they feel confident in their interpretation. If I had a paid account with NFPA, I'd open a technical case, but that will cost me $175 for the membership, so I'll have to think if that's something I want to invest in. Certainly isn't...

I read you loud and clear and will keep that present in my mind during discussions. That said, if the electrician did not run load calculations at time of service upgrade and sized the conductors for 180A, is that permitted?

Thanks, Wayne. You've really been great to me - and I appreciate your support. Your explanation of 310.12(C)'s existence is excellent and crystal clear to me. I couldn't agree with you more about needing to read (and think) more carefully. I'll let you know what progress I can make with the...

I am actually trying to get the electrician to upsize the 4/0 Al conductors to be what we believe would be compliant, as I don't think I should go hire a second electrician to do it. But... if I have a licensed electrician as well as the county electrical inspector telling me they are in...

The issue is that the county is saying there is no need to ever go beyond 4/0, regardless of my load calculation or measured loads. So, I don't know if I just let that liability sit on the county and assume I'm fine up to 200A on the existing conductors, or if I try to convince the inspector...

@wwhitney Last week I was finally able to have a conversation with the electrician who performed the service upgrade, and he was pretty adamant that the feeder conductors between meter socket and main disconnect should be 4/0 Al. His rational was that the last sentence of 310.12(B) reads "If no...

Thanks. Definitely noted on the corrosiveness of the water with copper.

Thanks, guys. Sounds like a drain is highly unlikely, and that was the part that would be a hassle, but need to happen now. She's working on picking out a couple options now, and looking like plumbing is nil and electrical isn’t anything special. Some of the ones I had looked at myself...

That is true - I have it in writing, and all I need. Though I'm thinking more about how broader humanity is impacted. I'm only mentioning the below rant, as I'd value your below input if you think there is a valid NEC PI submittal, coupled with a reach out to Xcel senior management. I awoke...

I think I've now dealt with 5 people at Xcel or their contractors that are not clear about it. You can hear it in their voice when talking to them. It seems that NEC and POCOs need to do something to add clarity. I awoke this morning thinking about that more... it seems like NEC should include a...

I realize that is an odd number for a single EVSE. I don’t actually have any EVSE yet :) but, as a condition of the permit I have to pre-wire or put in conduit. Since EVSEs seem to be going through their own evolution now (single breaker pool, load sharing, energy mgmt, etc) and we are a year...

Hoping you all can shed some very high level info on the topic of plumbed coffee makers for me. Admittedly, I'm not a coffee drinker, but my wife is. She doesn't have a plumbed coffee maker now, but as part of the remodel wants to be able to accommodate one in the future. She doesn't have one...
