That's a small problem, Dave. Here in NZ a maintenance crew removed ALL the bolts in three of the four legs of a 220kV transmission tower. When it fell over the northern part of our country lost power for several days. And you think it's difficult to get good staff!!

@@GameBacardi No, it was routine maintenance gone wrong. It wasn't the bolts that were removed, but the nuts. In this sort of installation the bolts are anchored in the foundation in the ground and stay there. The tower has a baseplate which sits on the foundation, with holes that the bolts go through, and nuts to hold the tower down. Periodically as part of maintenance, the baseplate, bolts, and nuts need to be inspected and treated to make sure they're in good condition and stay that way through their design life. As part of this, the nuts need to be removed, cleaned, treated to prevent corrosion, and put back (if they're in good condition, or replaced if at end of life). But under normal maintenance, you don't remove them from three legs simultaneously, and you make sure to have measures in place to keep the tower from falling over while you're doing the work. Removing more than one at a time requires an engineering review. The utility contracts this sort of maintenance on 200 baseplate assemblies a year, and this is the first time in living memory that this has happened to them. Unsurprisingly, the three person team who was onsite performing the maintenance has been stood down, and an incident review is ongoing, though the first priority is getting the power back on.

Had solar panels installed in the UK and they fed the inverter output direct into the grid so we had to pay for all energy produced, even the solar energy. I had a talk with there guy over the phone and he said it was wired correctly "I did all the calculations" I said well they are wrong! The same guy came around and inspected it and said it was correct, then gave me some bull about if they wired it into our consumer unit side that "The resistance of the wires would increase and the insulation would burn off" I couldn't believe the crap this guy spoke. Anyhow another visit by their "Best electrician" resulted in a slight change of wiring but still it went direct to the grid!. A few more calls to the local council and eventually someone came around and inspected it again. This time the council guy looked at it and couldn't believe what they had done. So eventually it was sorted. I've no idea how many other places were done incorrectly or even if they had them put right afterwards.

I was in the process of replacing the vanity lights in a bathroom when I saw some odd behavior. The fixture had 5 40W incandescent globes. As I removed the bulbs, I noticed a dim glow from the remaining bulbs. When I was down to the last buld, it was glowing brightly. I wanted to move the location of the wall switch as it wasnt by the vanity, but several feet away behind a door. In the process of doing that, I found that the 'electrician' who installed the attic fan for my radon system wired its power *across* the power switch. So when the switch was in the off position, the light and the fan were in series. When the switch was on, the fan was shorted. I corrected that while i was in there.

I've been having a new laundry building installed and as part of that we had underground power run over for a couple power outlets and a light. As part of that I initially had the building wired through one circuit but I decided to swap it to another circuit as the initial circuit had a fair bit on it. That led the sparkie down a rabbit hole as when he turned the light on in the new building it would trip the breaker but the Philips LED bulb would still glow dimly, and there was still 67 volts on that circuit. Turns out whoever had done electrical work long ago (This is an old house) had stuffed up and had the power running through a breaker and then through a safety switch, so about half of the circuits had no safety switch. I'm pretty safety minded around things, but I'm just glad it got discovered that way and not when someone got zapped. I guess it's no wonder that self electrical work is illegal here in AU, the monkeys can't use some common sense and eventually they got sick of people being stupid. I'd call for a basic competency test you can take where you can at least just put a new plug on without calling for a sparkie, but that'd never pass with the amount of monkeys out there.

If the solar installers were honest they wouldn't make one sale. In order for it to be worth the cost you would need to know the entire system how to maintain it and purchase your own panels and inverters. The other main problem is the efficiency is not there yet. if you only use $100 a month in electricity you cannot justify the investment except maybe a small system for power outages but other than that just not worthwhile. the only way this became a lucrative industry is from subsidizing a still flawed technology efficiency wise.

In those cases you should be installing ferrites on the supply circuit that would improve comms by keeping those signals internal. No excuse though, you don't leave the site lying about it.

Not an installation fail but a manufacturing one. Had a Pug 205GTI (UK) back in the late 80s. The heater blower didn't seem to be as fast as it could be on the highest setting so I pulled the controller out to have a look see. Speed control was done with a simple variable resistor and TO-3 Darlington. Also on the board was a relay and driving cct - 4 resistors, 2 transistors, 1 diode - that detected the 'full speed' setting and bridged the Darlington to give the full battery voltage across the blower motor. Problem was the necessary battery +ve connection it needed to operate was missing from the harness. There wasn't an back-EMF diode across the relay and I now wonder if the +ve connection was dropped because the relay driving transistor was getting blown and instead of fitting the diode they 'cured' the problem another way.

Not unbelievable at all. Australian industry is more into preventing people from working and policing political correctness than actually producing anything useful. Oh for the 1980s and 1990s. This is a nation in decline.

A few years back I had a door to door solar sales guy tell me he could get the new German panels that worked at night. Not the smartest nut in the solar industry. Next time I am going to tell the guy that I am interested but could they mount the panels in the attic, they are ugly on the roof.

D2D scams like this are everywhere, the common terminology is a Devilcorp, its not a religious thing its just a bunch of pyramid scheme companies that use cheap labor (100% commission lmao) and cult behavior control to sell cheap products in costco, sell you insect treatment or fiber internet D2D, and stand at street corners collecting "charity". Anyone who volunteers to tell you about the business they own and how much better you would be working for them is %100 part of this scheme.

You should have got it in writing and not paid until it was working at night. Free solar!

Well, PV panels do work off moonlight. The only downsize is that you're gonna get something like 0.30% of the rated power output.

Had a roof replaced and had the attic fan replaced at the same time. This was in the fall. Spring rolls around and the attic fan isn't coming on. I went up there, pulled the cover off and it wasn't connected.... I called the guy and told him about it and he said, "I'm not an electrician. I don't connect them." I connected it, sent him a bill for $100 for my time and he never paid it. I paid $10,000 for the roof and he couldn't add in an electrician to wire the fan? Or at least tell me about it?! What if I were an 85yo widow lady who wouldn't know the difference? She would have paid for the fan and higher AC bills for the rest of her stay in that house because of this guy.

This is complete madness. The only reason you found this is because you're able to figure out and diagnose stuff, and thought to look inside the box - and aren't afraid to open it. Imagine being Mr & Mrs Random Homeowner who doesn't have a clue. It'd take weeks to figure this out. Especially if they think the system is working.

that's literally why one Solar vendor here is gobbling all the sales, they sell an equipment that does remote telemetry, people want that because its the only way they can know the system is working as expected. because of moron installers like those who did that job, may I say, didn't do their job.

The fact they dismissed the lack of readings as the software not working tells me what I need to know about their trust in their smart system...
@jaykoerner3 ай бұрын
Didn't seem like they dismissed anything, they investigated it from the software because that is likely the fastest way to verify a problem(can be done instantly and remotely), that and Dave had been told by the installers that the reading might be off for a few days, if he had communicated to the enphase it is reasonable to look at it from the software first, This is the same thing ISPs do when you communicate internet problems

Correct. Enphase also had Solar (Dis)service Group (now Solar Battery Group) as Platinum Installers back in the day. Now all the Enphase Support team does is deal with warranty claims from previous Solar (Dis)service Group installs. They were shocking.

So do they pay your electric bill for the missed days? lol I'd love to add this to my house just for 'self-reliance', but it's not worth it. I don't use enough electricity to have it paid off in my lifetime (unless I built it myself)
