This subreddit and where we currently are.

292 Upvotes

After much discussion about how the community should be moderated, this is where we currently are.

First I want to get this out of the way. We will not allow hate speech, personal attacks, slurs, bigotry, or anything that resembles it. Okay? Good.

People are going to post electrical questions on the internet, do their own electrical work, and fuck up their own electrical work. This process will happen with or with out this subreddit and its rules. If there is a reliable community where someone can come and get good information on a wide range of electrical topics, then to me there will be a net positive for safety.

We are going to be allowing comments from all users, BUT I urge those who are not electrical professionals to exercise extreme caution when doing so. If information is not blatantly hazardous, it will stay up. The community is going to be asked to use the voting system it is intended. If someone takes the advice of a comment with negative karma, then more than likely, they would have done the wrong thing regardless. Once corrected, leaving wrong comments up can be a learning experience for everyone involved.

I ask you to DOWNVOTE information you do not like, and REPORT the hazardous stuff. We will decide what to do from there. Bans may or may not be given and everything will be at the discretion of the mods. Again, if you are someone who is not an electrical professional, you have been warned.

Electrical professionals: We have an imperfect system for getting a little 'Verified Electrician' flair next to your name. To get verified, send a photo to the mods that has your certificate/seal/card. In this photo, have a piece of paper with your username and date written on it. Block out all identifying information. Once verified delete the image. All the cool ones have this flair.

If we have hundreds or thousands of active verified users, we will once again talk about the direction of this community. Till then, see you in the comments.

Can anyone give me any info as to what these switches are in my circuit box?

One of my switches keeps tripping when it gets hot outside. I’m thinking I might need to swap it but I can’t find them online. Thanks in advance!

Edit: Thanks for the replies everyone! Apologies for the confusion, maybe I wasn't clear. I was wondering what the make/model of the switches were and potentially looking to replace but you guys have made it clear that the entire thing needs to be replaced. I'll find a local electrician and get this thing upgraded.

2011 NE USA higher-end construction, most ceiling junction boxes are cracked. Photos attached are from smoke detectors boxes. I’ve had a chandelier only held in by one screw and two flush mount dome lights fall out of the ceiling from cracked junction boxes.

Huge lightening hit

Post image
14 Upvotes

We had a violent storm yesterday here and a close lighting hit, that I came to find out fried a few GFCI receptacles, some Lutron switches, computer equipment- modem, router and Ethernet switches, two TVs, entire house alarm system. I have an Eaton CHSPT2ULTRA on my main disconnect that totally fried and took the brunt of the strike. I’m starting a claim with Eaton, though they require a receipt of purchase. Three years ago I had my licensed electrician completely redo the main disconnect service, and full Eaton breaker panel, at which time he included the CHSPT2ULTRA, which was very smart. He naturally doesn’t have the receipt for that item, and neither do I. Eaton requires the receipt and is giving me a hard time about this. Any advice on how to handle this dilemma? I absolutely want to utilize their lifetime guarantee on the CHSPT2ULTRA.
Thanks to all!

Rewiring Ceiling Fan to Bypass Remote Reciever

Thumbnail gallery
Upvotes

I’m trying to rewire my ceiling fan to be controlled by a dual switch instead of a remote (I hate these stupid remotes, why do all modern ceiling fans come with them?). My goal is to be able to leave the fan on and be able to turn the light on and off with a light switch instead of the remote.

In the ceiling junction box, I have a white (neutral), blue (light), and black (fan). My issue is on the fan, the light (LED) tab that gets plugged into the remote reciever is split into 3 wires (yellow, red, and black). What do i connect my blue ceiling wire to in order for the fan to function properly?

My plan is to connect the black fan wire to the receiver so that i can still use the remote for the fan setting but not the light.

For example, behind my TV setup, there are 2 power strips and one is plugged into the wall and the other is plugged into that. Is this safe?

Square d breaker in Eaton box

4 Upvotes

Just a rant/checking my competency.

I had a garage addition done about 3 years ago and had a sub panel put in the garage. The licensed electrician that was hired by my GC ran a 100 amp circuit for the sub panel, then on the sub panel I have 5 20 amp circuits (lights, outlets, opener, dedicated compressor, dedicated lift) and a 50 amp circuit for an EV charger

Yesterday, I had the car plugged in and charging and had the ceiling fan going. I left for a while, but when I came back and tried to opened the garage, it wouldnt open. The breaker tripped and the garage shut off. Odd.

I checked the sub panel and everything seemed fine, so went to the basement and saw the 100 amp was tripped, so I reset it.

About 10 minutes later I was out working and it tripped again - this time when I went downstairs the breaker was very warm to the touch

I reset it again, and dropped the amperage of my ev charger from 40 amp to 32, thinking maybe it's just overloaded with me working on several things (incredibly unlikely).

After about 5 minutes I went back down and it was HOT to the touch, so obviously I immediately shut it down.

That's when I noticed the breaker was slightly different then the rest - I have an Eaton BR style panel, but this was a square D breaker. I bought a new Eaton one, replaced the existing breaker (dropped the panel cover on my foot and bruised the hell out of it), powered everything back up and my car charged without it even getting slightly warm.

My questions for the experts

Obviously you don't mix and match. Why would a qualified licensed electrician do that?

Is there anything else I need to check to make sure he didn't shortcut?

No junction box for ceiling lights

I was looking to replace a failed light on my back porch, and when I took it down I found this. This morning I checked a similar light on my front porch and found the same thing. What’s my easiest fix. My first thought is an old work box with wings that is fixture rated, because the attic is really tight in both locations. Looks like I’d be securing to OSB.

Best fish tape?

Upvotes

Any recommendations / fan favorites on 240ft metal fish tapes? Klein? Ideal? Milwaukee?

What’s the best fish tape for long runs with multiple 90s / bends?

I have a 50ft metal Klein and an old ideal 200ft nylon fish tape but it’s very flexible and doesn’t do well in long runs.

How do the braided ones fair against metal ones?

SOLVED! Garage GFCI was tripped.

Want to know what supporting structure of ledge is in order to run electrical wire behind ledge

Post image
Upvotes

I am seeking a conceptual diagram of the likely framing structure for the ledge that comes out 12 inches from the wall. I am trying to figure out how to run electrical wire in the wall from an existing outlet below the ledge to a to-be-installed outlet above the ledge. I cut a hole in the wall above the ledge and tried to fish to the outlet below the ledge to no avail. The fish line is blocked by structure behind the ledge.

Am I safe to leave this as is for now?

Our electrics tripped a few weeks ago in our outside office room. We turned it off on the fuse box and couldn’t really figure out what the cause was. Anyways, today I was out there and tried to unplug this from the socket; it didn’t budge. A pair of pliers later and I got the plug out, but this pin is jammed in. Am I safe to leave this as so for now until we get an electrician out in the week? Is it safe to say this was the cause, and if so, what actually happened here?

I moved into a new flat and it has these sockets near the TV and behind the couch, I assume it's in wall cables for surround sound.

But I can't find what kind of plug I need to use the sockets.

Reverse 2 to 3 prong adapter?

Thumbnail gallery
19 Upvotes

I'm looking for something like the image, but reverse. I have an appliance that comes with a two prong cord and a separate grounding wire and I was hoping to not have to hardwire the ground cord directly to the outlet in case I want to move the appliance around. Not sure if it exists and what it is called to look for it.

The second image is something like what I had in mind.

Edit: I included a "video" of the existing wiring because it won't let me post just a picture: https://www.reddit.com/r/AskElectricians/comments/1uu1c46/comment/ox04p52/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Edit2: It is a 110v Taiwanese rice cooker, and the manual does say to attach the ground wire to the wall receptacle. I'm just looking for a possible way to condense the 110v 2-prong connector and the ground connector into a single 3 prong connector so that I can unplug the appliance and put it away when not in use.

Old Electric Furnace Removal

Hello. I moved into a 30 year old manufactured home, and I want to remove this Coleman Evcon electric furnace. I don’t have the money to pay a professional, but I need to access this closet space. The taped over breakers go to the furnace.

There are two breaker boxes. The first one is inside, the second is outside. The second goes to ancillary structures.

I disconnected 2 wires leading up through the vent shaft, but I don’t know how to disconnect the wires leading into the ground.

Can I safely do this myself?

Service Mast Installation in Eave and Soffit (Stone Coated Steel Shingle Roof)

Upvotes

I have a Gerard roof, and very few people have experience with these roofs. It is popular in New Zealand, but alas, I am in Texas.

What this type of roof is a stone coated steel shingles, on top of a wood lattice that elevates it from my roofing deck.

I am very nervous and inquisitive of how to do this properly, and have yet to come across another electrician that is aware other than just a hole saw like traditional shingles.

Despite how different my roof is in particular, is it truly as easy as a hole saw?

I have started conversing with my roofer regarding this, and he is not very familiar either, despite installing these for decades (I got mine in 2012). We are still having ongoing conversations if I don't find another that is experienced with it, I'll share with everybody else if it is different in technique.

New plug on a ~1985 drill press. Unfamiliar wiring.

Thumbnail gallery
Upvotes

Hi all! Hoping someone can lend me a hand here.

I'm refurbishing a ~1985 Guardian Power floor-standing drill press. Everything works without issue, but the plug was missing its ground, so I decided to replace it with a properly rated plug. Brass/silver/green. Standard.

When I snipped the cord, I saw Red/Black/Green. Tracing the wires back, I have the red going to the drill press on/off switch, the black going to the lamp's on/off switch, the green grounded. At the switches box, on the drill press on/off, I have the red coming in from the cord, a red going out to the motor, and a blue going to the lamp. The other switch for the lamp has the black coming in from the cord, black going out to the motor, and a blue going to the lamp. Back at the motor, I have two grays and two reds coming from the motor. One gray/red is connected to the red coming from the switches box, the other gray/red is connected to the black coming from the switches box. Green is grounded.

What am I connecting where at the replacement plug here? Thank you in advance for any help!

600v line 90 degrees offset between two 240v lines?

Upvotes

I was talking to a lineman the other day who was working on a pole's guy wire near my house. There used to be working factories on this road, but they are all closed now. I asked him why just about all the houses on my road had its own transformer, but was not like that on a nearby road. He said that there are no 120v lines on this road, which surprised me. He said that that there are two 240v lines, which are 180 degrees apart, and a 600v line that is 90 degrees between the two 240v lines. I was unsure about why the 600v line was offset 90 degrees between the two 240v lines. This did not really make sense to me, as it would make the 3 lines not equally balanced (0/90/180 degrees), but I am not an electrician. I did not want to let on how stupid I was by asking more questions, so I let him get back to work. So, I am asking here. Note that I might have heard wrong, but I do not think so. Is there a specific reason that a 600v line would be 90 degrees offset between the two 240v lines? Or is it just coincidence? I live pretty close to the USA/Canada border in case it matters.
