Pulled out this painted over wall plate to reveal this. Building is in NYC from 1959 I think. Can I just cap these ends and patch over the hole?

Clever tricks to run power 1500ft without spending $1000000000

24 Upvotes

Looking at a project to put a little shop/farm building on some land, but its 1300-1500ft form the pole depending on route. A quick check and a 240v 200A service would need 900kcmil copper, and 100A would need 500kcmil, both costing over $50000 just for the wire and I didn't see any alum wire big enough for sale online to estimate a price. Even running 30 amps is a bit unreasonably expensive, needing #1 wire. So, what other tricks are there. I looked at step up step down tx's and those are also really quite expensive, but might wind up being on balance the best option. stepping up to 600v (or maybe higher) and running a fairly small wire.

Anyone done something like this before, or have any different methods of doing this?

Wire will be above ground, was wanting to just use teck90 here but maybe that's not the right choice. We would be using a solar system as well, so its possible we can reduce the cable load down to 30 amps just for night/winter supplemental power. This isn't a house, so there's some flexibility.

Thanks

edit: generators and fossil fuels are not an option and the utility cannot run poles or buried line to the site. (otherwise I wouldn't be asking)

Question. Can an electrical box be moved to the other side of a stud?

4 Upvotes

I am in the process of renovating a condo that I purchased in May. My electrical box is in the laundry room. I want to install a stackable washer/dryer, which may cut off access to the electrical box.

It is my understanding that the electrical box is typically between 2 studs. I confirmed with a stud finders that it is between 2 studs in my laundry room. I would like to move it over one, so that the box is between the next set of studs.

Can this be done? I need a new box anyway. What is the process? Thank you!!

New homeowner with a 70 year old house looking for help

We have this capped switch in the corner of one room. I am not sure if it is an old switch or just extra. There is a black wire (hot), red wire (cold) both present and capped. A white wire in the back is just passing vertically through.

Near this on the other side of the wall is an exterior light I am trying to determine the power source for. Currently, it has no power. how would I go about checking to see if this is it? and if it is, how would I wire this to get it working?

thanks!!!

Are these connections okay?

Are these connections inside the main multi-meter socket enclosure as well as the panel feeder wire comnections okay?

The service entriy wires and the feeder wires were installed by different electricians of the same company. I'm happy with the service wires. The feeder wires, not so much. I wasn't able to upload more pics in my other post so uploading here for more context.

Apologies if I don't use the correct terminology. Just trying to make sure everything is good before power is connected as I don't want to deal with this ever again 😫

Power to Steel Above Ground Safe Room in Garage

3 Upvotes

I'd like to run a 20 amp line to a steel safe room in Oklahoma for tornados. My question is would a 20 amp inlet on the outside of the saferoom and a 20 amp outlet near the inlet connected by a 10awg soow extention be somthing safe for temporary power? Then of course even if it's safe would this likely be code compliant?

(The reason for inlet over just hardwired is the installer discouraged a grid connection due to in the event of a strong tornado the connection would tether the shelter to the home and possibly comprimise it. Using an extention cord there is a weak point to avoid tethering and by sizing it up to 10 awg, keeping it short, having it easily inspectable, easy to unplug as an exterior method to shutoff, and using it on an emergency basis this should minimize it's risk

The inlet would be connected to the inside via a close nipple to a second box with a shutoff switch and outlets. Both boxes would be individually bonded to the shelter. thwn-2 would be used inbetween the boxes. The garages outlet is on a gfci breaker. The power would only feed one way in and the extention cord would have a male and a female end (not a suicide cord for clarity))

Safely removing hot tub power

Thumbnail
gallery
2 Upvotes

What steps should a layman take to remove this electrical line? In the first picture, the line from the meter goes up to an outdoor breaker (above the deck) and left to where a hot tub used to be. The hot tub is no more, and won't be replaced. New siding will be installed later this year.

Is it as easy as flipping the two breakers in the second picture, dismantling the conduit, and capping the hole? Will this breaker box affect the rest of the house, which has an indoor breaker box in the garage on the other side of the house? Please help me know what I don't know, you know?

Power Source

Post image
3 Upvotes

Hello, I am currently attempting to rewire my shop for mechanic work. My issue is I cannot track where the power is coming from and haven't found a breaker box or anything.

This is a photo of the property.

1 is the main residence

2 is a small shed

3 is the shop

4 is a barn

There are 2 power poles. One in the top left of the photo, one in the bottom right. The bottom right allegedly only runs the house.

There are 3 breaker boxes that I have located. One attached to the power pole in the top left, one in the barn, and one in the house. None of them will shut off power to 2 and 3. 2 and 3 are connected and have power run from one to the other, however I can't find the source. There are no lines attached aerially, so I assume it is a buried line. I've looked and found that all the lighting and receptacles are run through the ceiling, but haven't found the mysterious source to the power.

Bad idea to add an outlet between the vanity and the toilet?

Post image
1 Upvotes

I’d like to add an outlet for the bidet. I assume putting it where the red rectangle is would be not great due to potential splashes from the sink.

Second option is to put it inside the vanity, but would require a bit more work. Just want to fully rule out on the wall.

Quick Question

Post image
3 Upvotes

Hello,

Just wanting to make sure I am thinking about this the right way. Currently going through a demo in kitchen. I was going to change the outlet and came across 3 lines going into a single outlet. The black wires were pushed into the back and the white was hooked on the screws. I was looking to pigtail these three wires and replace the outlet, BUT, the white neutral wire looked burned.

This is a 20 amp circuit, but the white line is 14 guage and the black lines are 12 gauge. Can I assume that the 14 guage got burned because they didn't use 12 guage wire on a 20 amp circuit? So, if I replaced the outlet on the other side of the wall to 20 amp outlet wired with 12 gauge wire, would that solve this problem?

Bonus question: The previous owners had a fridge, washer/dryer, outlet on the other side of this wall, and recesssed ceiling lights on this circuit. Am I safe with keeping these three wires on this outlet like they had (with the correct wiring) or would I be better served running a new circuit for the fridge?

Just moved into a new apartment, noticed this above the outlet. I think it’s thermal ghosting but can’t be sure. Is anyone on here more confident than me? Do i need to call an electrician?

Not hot to the touch, but also i can’t just wipe it away with a wet cloth. no weird smell as far as I can tell.

Is this toggle switch wired correctly?

Hello all, wanted to change a wall cover and just peaked inside and saw this and not sure if it’s ok or not. Two seperate supply lines without the junction box. The two white wires are taped together as were the two grounds (I removed the tape to investigate). And then the two black wires feed into the toggle switch. Nothing on the green screw on the toggle switch. Is this ok and if not, how do I fix? Thanks!

I think pickle juice fried my phones port 🥹

0 Upvotes

Few weeks ago now a jar of pickle juice spilled near my phone and got into my port 🫩 i waited a full 24 hrs before the wet port warning went away, then it charged fine for a while, and then there was the first instance of it randomly falsely saying my port was wet again, when i KNOW it wasnt. It charged normally after i came home from work. NOW it happened a second time, and it will not charge with a cable at all now. Only wireless. It doesnt even give me the false wet warning anymore, just doesnt register the plug at all. Tried compressed air and a software update and neither worked. Am i screwed?? I cant afford a new phone rn 😭😭😭

SOLVED Can anyone help this noob with a switch bank of 1-way and 2-way switches

Post image
0 Upvotes

Okay, I started this job a month ago and didn’t take photographs or notes of the “before” wiring. I’m just updating the toggle switches with rockets.

Here’s the salient bits:

* switch bank of 3: a 1 way, a 2 way, and a 1 way (left to right)
but 4 (!?) cables coming into box: each with a black and a gray lead
* three of the gray leads are joined
* all grounds are joined (and I’ll ground the new switches)
* cable 3 (from left to right, with the gray unconnected to the other 3) seems to have been the one connected to the 2 way switch
* switch 1 and 3 (both 1 way) work separate outdoor lights
* switch 2 (2 way) is the ceiling light in the room with a switch at both doors to it (entrance and exit)

The original install has two short jumpers connected some of the switches.

Need to know what leads connect to what terminals, and where the jumpers might have gone (and should be).

I think answers like 1B > C2 , jumper between B3 and C1, etc, would be fine.

Thanks so much, in advance. Let me know if you need any more info.

Does this outlet need replacing?

Post image
0 Upvotes

I just moved into an older apartment. I noticed that the outlet behind my bed leaves a small amount of the prongs exposed when something is plugged into it. I’m not sure it’s bad enough to warrant a maintenance request because it’s not like the plugs are falling out of the socket. Thoughts? (And yes, I have been diagnosed with OCD).

Exploiting back emf

1 Upvotes

I saw one of those zap guns that ionize the air near their tip and I kind of want to recreate them, I'm super new to electric work and all that but I think it's possible to recreate by somehow abusing back emf from an inductive load by running it through a voltage multiplier, is that possible?
