It's a giant open battery on the floor. There's no equipment that's going to deactivate it.

Blast from the past... in a prior life I worked in a battery factory, where we had 50 tanks in series forming battery plates in very dilute sulfuric acid. Basically an enormous 50-cell battery. Floors were always wet. Sometimes a plate would short within the tank and the watchman or whoever...

I'm not asking about clearing fault current. None of this was about that.

I did get that wrong - even though I was thinking about it! - yes, if nothing connected to the genset is grounded/bonded/connected to a GEC then what? Dude with genset running beer fridge and TV on the back porch during a power outage. I saw something about SDS' over 1000 VA needing a GEC.

Under what circumstances is the grounding lug on a genset needed? And grounded? Nothing that's plugged in has an ECG. Isn't one needed to keep the whole system voltage referenced to the surroundings?

Similar question here. Actually two of them: 1) Question for today: BIL has a new battery bank for his house and is running cables to be able to charge the batteries from a generator. This should not be needed in normal operation (unless a power outage extends multiple days) but he wants to rig...

They don't make the same style as the 4x4 with the cover with crushed corners. At least, I didn't see it in their online catalog. If you have a link or a PN, I'd love to see it.

I assume you also want the raised cover with corner screws, like the drawn 4x4s get? I'm with you... a few weeks ago I spent some time looking for that, too. No one seems to make a 3-gang equivalent of those nice drawn 2-gang boxes with matching covers. The missing part is the cover; all of the...

I totally get it. If the engine itself isn't the issue, then warm the cabin. That heats all of the glass, so no scraping.

The last "new" slides I bought got under warranty were greased with a translucent yellow grease. I had some old slides (from when I bought the boxes) that were gummed up and I needed to clean them, but the biggest problem now is the deteriorating bump stops. My driver has given me a bag of the...

In my field (BMW motorcycles) things have changed over time. For M6, 11mm hex became 10mm. For M8, 14mm hex became 13 and very occasionally 12. M10 cylinder stud nuts actually went the other way; we had 14mm nuts that deformed too much and became 15mm. For non-specialized M10, though, can be...

I'd be checking the overall voltage regulation over time to look for an answer. Yes, if the other three batteries never see more than the usual voltage then they shouldn't overcharge, but if the VR sees the overall voltage drop (acting like an undercharged battery) and boosts the output again in...

I initially bought some 1st-gen Levitons but they just were not reliable. I think I got refunded AND they sent me some replacements which I may have given away because I just didn't want to go there again. These were specifically the HomeKit ones. I hear the 2nd-gen were much better; maybe the...

How reliable have your Wemo switches been? I bought some about six years ago (I posted here at the time) and for a long time they were fine. Every now and then one would go offline, but usually some time would cure that. Then about a year ago one of them went offline and couldn't be brought back...

Thanks. I found a different version of that one that has the HP rating I need. Which valve did you use? I looked at them a while ago (for water, not air, but I would like one for air) and almost everything I found seemed to be a differently colored version of the same valve by US Solid.

I have a few Wemos that are working through HomeKit and they should be OK for a while, but over time I'm sure they will be unsupportable by me if they lose their config or something like that. I'm gradually switching over to Lutron Caseta.

Unless the pop-off valve goes bad. Happened to me a few years ago. Came in to find the compressor running, air roaring out of the valve, and everything in that room HOT. So I want to control it with a low-current 120 to 240V solution. Smart switch, tied into lights, something like that. Any...

We have a few eyeball lights in one room with ELCO EL985W trims, which are supposed to take PAR20 bulbs. I have bought two different PAR20 bulbs and they will not fit into the clip ring. The original SATCO bulb is exactly 2.5" (within 1/128") but I have bought two different PAR20 bulbs that do...

I don't remember if it was BX or not. This was farm country (probably 15~20 minutes from the OP) in the '70s and I bet a lot of people were not using electricians.

That house (1942 comes to mind) was all 2-prong and because 3-prong cords were new on the market in the '70s people were switching outlets to 3-prong tying ground to neutral just so they could get on with things. The house I'm in now - 1930 - still had a lot of knob & tube when we moved in...
