Seems like burrowing with water for a ground rod would defeat the purpose - you'd end up with poor soil contract because of the large hole you've made flushing out the mud. I have seen that trick used to dig under a sidewalk, works real well.

Right, but the undisturbed soil is what gives good contact with the ground rod. In utility work, when attempting to drive rods in very rocky earth, sometimes they must drill, or drive into poor soil and make a hole sort of like how you describe. And then they have this stuff they mix and pour down that is basically very conductive mortar. Even if you completely filled and tamped a hole before you drove a rod into it, it wouldn't have as good of resistance as driving into undisturbed soil.

So they aren't going to put any kind of wall cover or moisture barrier or anything on that exterior wall??? Just a brick veneer over the stud walls?

Could you take a few samples with a drill bit, see what the core of the beam looks like, or at least how soft it is? I lean towards leaving it, if you can verify that it's sound.

You know more about construction than me, but it seems like that beam is wrapped such that if condensation forms it will have a hard time evaporating? I remember an episode of This Old House where Tom Silva talked about how old houses had walls that could breathe - and some new construction houses, with layers of vapor barrier on both sides could not and he wondered about condensation and decay because of it.

I've been involved in a couple auto transfer setups in my commercial electrician days, and seen quite a few since, as well as a solar array interconnected to utility power, but I've not personally seen anybody switch the neutral. Since this disconnect is to be installed after the meter can, the neutral and ground should be separate at this point, which would require a 4 pole switch to be NEC compliant, and accomplish what you are intending I think. angryrobots fucked around with this message at 03:15 on Nov 12, 2014 |

kastein posted:first paragraph - cool! Some power companies want to see a switched neutral in residential work with an ATS involved. I can understand why, if your premise wiring is hinky as gently caress (which can basically be guaranteed on anything more than 10 years old with at least one JAFHO involved) there's no guarantee that your goofy wiring and generator might not backfeed a couple dozen volts onto the neutral and fry their poor lineman, so I'm interested in switching my neutral even though my local company really doesn't care. Splitphase, residential service. In the meter can, neutral and ground are connected, same bus. So if ground is continuous and unswitched at the disconnect, if you bond anywhere else, including at the generator which I believe is necessary with a switched source utility neutral, then your house/generator neutral is still connected to utility neutral regardless.

Well, keep in mind the intent of the grounded/grounding NEC rules - you want fault current on ground to have the best and shortest route to the source, enabling the fastest and most reliable operation of the circuit protection device. I would not suggest being bonded beyond the meterbase, for reasons of creating a convoluted path to the utility neutral for fault current during normal operation. Here's my thing - say worst case the generator is completely miswired or fails internally or whatever. Any 'voltage' that finds its way onto the neutral won't have any potential relative to anything past the bonding point. The 240v conductors are open at two points in your case (ats and external disconnect), and the neutral is bonded to ground everywhere on the utility side. Where can there be a potential difference on the utility to cause any harm? And I say this as a power lineman.

kastein posted:Service disconnect wiring: (supply from lower right, load to upper left. Since it is now pretty unequivocal where my service disconnecting means is, everyone should be happy to see the neutral bond here. I placed it on the load side. Secondly, when I'm looking at the disconnect switch there, the line side is fed from the meter can? If so, you are switching utility current.... From what I've seen I would not want any device operating unprotected utility current inside my house. The amount of fault current for the utility protection to kick in is astonishing. I would strongly suggest, when you upgrade to a 200a service, change out the meter can to a combination unit with an integrated 200a breaker. The 240v buses come straight out of the meter and into the breaker, absolutely limiting the utility fault current and keeping it out of your house. Edit: here's a couple examples of what I'm talking about. You don't want this kind of potential in your basement, nevermind the cost to replace the equipment if that's all.

kastein posted:They are? I thought the neutral was isolated there, since the code says to ground bond at either the weatherhead (hell no), the meter can, or the service disconnect - one and only one of the above. Since 95% of the time this means people put the bonding screw into the isolated neutral bar in the main panel (which is their service disconnect) I was under the impression that it was at least possible to get a meter base with the neutral bus not bonded to ground as otherwise most installations would be ground bonding in two locations, thus breaking NEC. In fact up until a few years ago, they commonly ran 3 conductor cable from the meter can to the main panel. My house is this way. Mike Holt has a couple pictograms for you:

Well and keep in mind that anything I think could be preempted by your local codes and inspector. But they can be sticklers for the NEC as they interpret it, while at the same time demanding something illogical. For example, for a long time electricians would have a short ground rod just stapled to the pole, when installing a temp service pole for us to hook up by the road. It's temporary, we had no issue with it. Then the local inspector demanded they install a full 8' rod because the NEC says so. Well, they don't call for locates before installing this temp pole and rod, and of course the inevitable happens and this electrician drives a copper clad ground rod straight through our 2" pipe carrying an energized 1/0 7200v cable. Fortunately the fault protection did its job and he had no idea that he just knocked out power to half the subdivision. I like the idea of installing the generator as a separately derived system, because ground fault current will always be traveling towards the source in either case.

Is that going to be your only/main source if heat? Sorry if that's a stupid question, I'm from The South where we heat with forced air. Anyhow, if that's 10k all in on heating the whole place efficiently, I'd say it's not that bad. I know it hurts but "done right" is worth it.

I've got a sign made up that says "free scrap metal", and I just put metal and whatever else that may not be completely trash by the road. I've easily gotten rid of 20 truck loads of crap that way. But that's an option when you live in the country and 80% of the traffic is pickups driven by persons who cannot control their urges when they see "free". Reuse, recycle, right?

Radiant heating is new to me. What does the newest plan mean for the high temp zone? It has perpetual limited output, at the benefit of maximum efficiency? Edit: or you're saying you will completely eliminate it? The line about "if I do not need the baseboard zone to keep up" has me wondering.

Er...the air handler in the garage is sucking return air from the garage? That's definitely not a good idea, especially if it's actually used as a car garage. The room should be sealed from the rest of the house, not potentially ducting carbon monoxide. E: unless this system is only for the garage area and does not tie into living space. angryrobots fucked around with this message at 19:35 on May 4, 2017 |

Yeah, you're right, that's it I'm sure. I read closet air handler and projected how I often see them installed, drawing air through a grill in the door. Although to be fair, as leaky as the return duct to air handler connection often is, it's not the best location for it. Something to be mindful of at least. angryrobots fucked around with this message at 23:37 on May 4, 2017 |

Darchangel posted:One of the first things I did after I bought my house was put in attic stairs. Built in 1964, bought in 2000, and no one had put in stairs in all that time. There was one little (I mean tiny) hatch in the garage, where the roof was lower, and difficult to get to the rest of the space, so I put a set in the hall. I have one of these Owens-Corning 541799 R-10 Attic Stairway Insulator, for Openings Up To 24.5 by 54-Inch https://www.amazon.com/dp/B002SYP8SA/ref=cm_sw_r_cp_apa_e28zAbGFD736E And I like it better than the zippered ones, because it moves completely out of the way if you have attic storage. It may not be "sealed" because the bottom of the tent is just sitting, but it seems to make a big difference. Installation is simply setting it in place which can't get any easier.

A few weeks ago, i had to peel some really awful wallpaper in a bathroom, that they glued straight to the unfinished drywall with no underlayment. I used a product to break down the glue, but regardless the wallboard took heavy damage in some spots. Our options were full tear out, or seal and skim coat (almost) the whole room. A dust-free drywall sanding attachment + a dust collection bag in the shop vac made this project a hell of a lot easier and less messy than I anticipated. If you need to repair damaged drywall this stuff is the poo poo. We had zero bubbling with primer or paint.

Just mentioning since I didn't see it anywhere... But there's an be imgur uploader built into awful app, and it works a lot better than anything imgur intends for you to use. I dunno if you're using smartphone pics or a digital cam though, so this may be unhelpful. IMO just post the h version, and if anyone wants to blow up your picture to find something obscure in the background to tag themselves, they can figure out how to copy/paste out the "h". Awesome work at ever. Stringers on stringers!

I've had several buildings gutter'ed professionally. It's definitely not a job that's worth doing DIY. Just find a reputable company who is willing to work with the downspout locations, attachment method, hardware, and materials that I'm sure you will specify.
