Is it considered safe to work on a receptacle downstream of a gfci after tripping the gfci but without flipping the breaker? It's on the load side, and tripping the gfci does show it as unpowered.

Florescent to led light replacement not working

I got GE t8 bulbs (double ended, direct connection) 4 foot led tube lights to replace existing t12 florescent bulbs. I removed the 2 ballasts in the fixture, joined all the wires from one side of the fixture and wire nutted them to the line, and did the same with the other side but with the neutral. I also removed the starters that were connected to the tombstones. I swapped out the florescent tubes with LED, turned on the circuit breaker, flipped the switch, and no light at all from the leds. Do I need dummy starters to bridge the connection in the sockets?

Pictures are from before bypassing. I forgot to snap pics after

Alternative Grounding for Apartment

Hi reddit,
New here and need your help. Currently my apartment has this problem of its electrical socket discharging too much current. This is due to the lack of internal grounding installation (long story short the normal negative wire were disconnected, and the building electrician has this bright idea of redirecting the currents to ground).

So i have been looking for alternatives, and apparently youbcan install grounding cables to electrical socket, and has the grounding rod nailed to the wall.

Now this is a bit problematic, I doubt I can get approval for doing something like this nor is it safe. The risk of nailing grounding rods to another electrical circuit or something else is too great.

So I want to ask, is it possible to make your own grounding media, say for example I fill a glass cup with table salt and put the grounding rod there. The glass cup would be sitting on my large wooden table, my floor is made of ceramic.

Tragic pickle juice spill

Managed to spill pickle juice all over the place and it managed to get on a power bar, laptop charger, iphone cable, and lamp cord.

Realistically do I have to throw these all away? This is like $150 worth of stuff. Can I replace the power bar and call it a day?

Electrical Apprentice Hiring event process question.

I recently attended a hiring event for an electrical apprenticeship with a non-union company. i did the whole math exam thing & I've already received the background check paperwork, so I think I'm moving through the hiring process.

The more I've thought about it, though, the more I realize I might be a better fit for some of the company's office positions instead of field work. I'm interested in roles like Contract Specialist, Procurement Specialist, Safety Manager (or Safety Coordinator), or Technical Recruiter. was wondering if there is a trainee position for those roles.

& My concern is whether bringing this up now would hurt my chances. Would the company appreciate knowing where my interests really are, or would they see it as me no longer being committed to the apprenticeship and potentially withdraw my offer? Is there usually any flexibility to move into office roles early on, or do companies generally expect you to stick with the position you originally applied for?

Hearing a low humming noise coming from fridge I believe

Hey folks, so my fiance and I were out of town for the holiday weekend, and came home to find out that our breaker tripped Saturday morning, and the kitchen was running without electricity since late Sunday night. I woke up this morning to hear a low humming noise coming from what I believe to be the fridge. Is this just the fridge cooling down, or is it something more serious?

Arc not trip breaker?

Hey folks! My husband’s uncle is here doing work for us on a gutted bathroom. He just came in and asked me which breaker was for which bathroom (we moved in a year ago, they are labeled “bathroom 1” and “bathroom 2”), and I told him he could just turn both of them off as the water is off anyways so we’re not really using the bathrooms.

He said he “tried to trip the right breaker by creating an arc but the breaker didn’t trip” and implied this could be a bad thing.

We lost our previous home to an electrical fire in Dec 2024 so this made me feel pretty nervous. I tried googling but it was confusing.

Additional context: We had an electrician do a ton of updates before we purchased (we couldn’t get homeowners insurance before updating at least the glass fuse box so we opted for all of the repairs recommended by our inspector). The original house was built in 1943 but the previous owners did a total of 3 additions/expansions.

The only electrical thing I’ve noticed since living here is we can’t run the toaster and the espresso machine at the same time or the kitchen breaker trips).

What exactly does it mean that the breaker didn’t trip (layman’s terms please lol) and is there anything I need to be mindful of or aware of?

Neighborhood powers goes out and breakers trip during every tiny storm?

Hi all. I moved into a new house (new build) and everyone in the neighborhood is currently trying to figure out what is going on. Every time a storm rolls through, even if it’s a tiny one and barely any lightning, our power will go out for a second, then immediately turn back on. It’s making our breakers trip. Sometimes it’s none, sometimes it’s just 1. A few neighbors have had all of their breakers on the panel trip at once. The HOA says it’s on the electricity company, (Gulf coast electric), GCEC says it’s not. Does anyone know what could be going on? Some neighbors that have lived here longer claim that this wasn’t an issue before they built the last few houses in the neighborhood. I am noticing this happening more in the last few months than I did when I first moved in. Once, the breaker tripped when plugging the vacuum into the laundry room, but I’m unsure if it’s related. Thank you!!

Woke up to this being stuck on “ test” mode

The reset button to the left works, but can’t seem to un trigger the button on the right. I don’t use that socket all that much and this is the first time this happened to me in 10 years. I’ve lived here. Any thoughts? and sorry for the amateur question.

Anyone know what’s going on here?

hoping to remove this small section of wall that is between two closets in a home that has been extensively renovated inside and hoping someone can tell by looking at all this what it is/was?

I don’t think any of this is currently doing anything but I have no clue and don’t know how to go about figuring that out.

The two wires that continue down and out of frame go through the floor to somewhere in a crawl space I can’t see. Thanks for any input!

Edited to just say thank you to everyone who responded, so helpful I really appreciate it!

Can I use 2x 20A breakers to somehow power my 40A 120v AC?

I am limited with my generator outputs, but my HVAC is less than 60A total. The fan is easy to power with a 20A plug, but the condenser outside is 40A 120v according to the side panel.

I seem to have 3x 20A outlets. Any thoughts?

Image attached of my 6000W gen outlets.

Update: Thanks boys! Figured I’d check. Fortunately power outages aren’t common for us, and this little buddy still powers the router, fridges, TVs, and gaming consoles as needed.

I’ll also mention a pro for tank water heaters is that the heat will last a couple days if you use it sparingly for quick showers.

Mysterious light switch

Hey guys, can anyone tell me what this switch might be hooked up to? My house was built in 1970 and there are almost no overhead lights but each room had a switch that controls an outlet. I put in new lighting and was going to hook them to this switch but im not sure what this is hooked to. It looks like thermostat wiring or somwthing. Any help is much appreciated.
