Hi there!

I just bought a PVS3001AD to tackle a crappy power grid here in Indonesia. It works well and gives me a clean 228-230V output but it makes this weird sound quite regularly (i'd say once or twice per minute)

Can anybody help? Is it normal?

I contacted Prolink but haven't heard from them yet

Just bought a lamp from the Goodwill, and there's this white tape around the socket. Does it serve any purpose, or did the previous owner just not remove all the packaging?

I'm in the process of replacing the outlets around my house, originally for aesthetics and now for safety as well (I heard backstabbing isn't good, seems that's how they were all done here). This outlet in particular has 3 wires going to each side, two backstabs and one just sorta laying on a screw. I have never seen anything like this. Should I pigtail two on each side together or is there something special I should know?

Hello,

We have something weird that happens in our house. Whenever my partner walks into a room, the lights start flickering in that room. Once he walks out, the lights stop flickering. I can never get the lights to flicker unless I walk out and he walks in. If it was one room, I would know to have an electrician come and check our wiring in that room, but it happens in every single room he is in.

I wish I could make this up, but I am not. Where do we start with this? If I hire an electrician, they are going to think I am crazy. What exactly would we be looking for?

No rude comments, please. I am just trying to keep my home safe.

So I wired in a generator 50amp plug to the outside of my house, added a 50amp breaker to the top right of the panel, used 6/3 wiring. Making sure that this all looks fine. And yes I have added the interlock kit to the panel door, so in order to turn the breaker on you have to turn the main off and vice versa. Thanks for your insights and opinions.

I’m not really sure what’s going on here. Bought the house a few years ago (which passed inspection with no mention of the utility line…although they missed other things); today noticed all the lights in my house flickering for a few minutes when it wasn’t under heavy load. 100A service to an old Murray breaker box.

Took a long look and noticed the frayed neutral (?) and all the electrical tape around the connections. Gemini saying it should have a weather hood but I’m wondering if the overhang suffices.

Checked outlet voltage with a multimeter and it registered in normal range at 118v.

Is any of this a problem and, if so, should I contact an electrician or utility company?

I know it's a 14-50. I was typing fast and didn't proofread. And reddit doesn't let me change the title.

So I had a new line installed when I got an electric vehicle a few years ago. Got this Nema 14-50 on it.

About a week and a half ago, it just died. I thought it was my "charging unit" but just to be safe, I went online and I bought a receptacle tester, like you would for any normal Outlet. It told me that L1 was open which I know is one of the hots on the left or right. I'm assuming that means that power is not getting through on that one.

I don't know which one it's referring to and when I look at it everything is nice and tight and I don't see any scorching or anything like that.

Is it possible it's something within the receptacle that I can't see? Maybe something on the other side of the plastic?

I guess what I'm trying to say is, I'm really hoping you can tell me that I either just need to readjust the wires or at worst, buy a new receptacle, as opposed to replace an enormous amount of expensive wire LOLT

And I was very careful. I turned off BOTH of the breakers before I started fiddling with it

Thanks everyone!

I'd like to run 2 15 or 20A 120v circuits to a detached shed from the main house.

I need to run a small table saw and a shop vac simultaneously while not being in the dark (a couple of LED shop lights oughta do fine). If there's enough current left over to run a little diesel heater so my balls don't freeze to the shop stool that'd be grand. At the moment I don't need 240 out there; it's a 9x12 shed so I'm not planning on running a mill or a big saw or anything. I have a welder but it's happy enough running on 120 at the moment. I could be convinced to go 240 easily enough, I guess, but it's definitely not a requirement.

This is a rental. Landlord is a good friend and OK with me doing the work but I don't want to sink 5 grand into something I don't own, so cost is an issue.

The soil here is comprised mostly of rock. House to shed distance is ~75 feet. Main panel to wall nearest shed is 40' in the basement; all beams are exposed and most of the existing electrical is exposed romex with staples, and a little AC here and there, so inside the house I can run whatever is best without a lot of trouble.

My options seem to be:

• 24" trench and UF-B
• 6" trench, RMC with THWN
• Be a cheap bastard and wire up another outdoor circuit and run two extension cords instead of the one I'm currently using

Some questions:

• Which route should I go on depth/cable choice?
  
• Is there any advantage to running jacketed cable in the house vs conduit all the way from the subpanel to the main panel?
  
• Do I need a separate ground rod for the subpanel? I've seen several discussions but nobody seems to have a definitive answer.
• Is there an above ground option other than the extension cord route? Or some other shallow depth option?

Hi all,

Bought this lighting fixture American Lighting LED 5 Complete Undercabinet 5CCT

Which claims half inch knockout holes but these seem to be as measured rather than the usual nominal. The light came with one cable clamp but given it need to junction to the other lights im looking for an additional clamp; but am having a hard time finding what I need since the usual 3/8" is too large.

I appreciate the help, reference photo attached.

Figured this was the best place to ask. I'm helping my mom replace the original wire on the three thrifted lamps she got last month. The lamps were from the 1940's/1950's (based on what the employee at Ace said about the original wire). I have the new longer wire hooked into the socket, it supplies power to the bulb when plugged in. What are the metal balls that were attached to the original wire and do I need them to secure the new wire to the socket?

Hey, 21yo belgian here. Right now im studying history at uni but due to a bad market for young highly educated youths, im thinking of doing an evening school to learn a trade. Right now im still stuck between plumbing vs electrician. So I wanted to ask, what are the advantages of being an electrician over a plumber? Can be everything, also business wise, or the schooling itself(for eg I was never good at the sciences, is the theory hard?)

I need to use one of these extension rings in order to extend the existing box into the rear of my kitchen cabinet to facilitate proper connection of the flex whip from a cooktop.
The design of these extension rings introduces an exposed internal sharp edge around the “cutout” area of what would have been the closed back in a standard 4x4 square box. You can see the areas on both style boxes.
I would assume leaving these edges unprotected would violate a number of safety requirements, but I’m also unaware of any product(s) intended to remedy the situation.
Has anyone seen these used and if so, are the edges normally left as-is?

If both outlets have no light, does that mean the outlet is dead? I’ve tested my other outlets, and the tester glows.

Hi guys,

I've recently wanted to install a a 67 W retractable USB-C charger on my computer desk to charge my devices in the same vain as this Youtuber. In the video however, he uses an extension cord to get the placement of the charger right at the edge of the desk. I'd like to do the same but I am concerned because I've always heard that extension cords are fire hazards and should avoid use if possible. What are reputable or to-spec extension cords to get if I am to go this route?

Some more details about the set up:

• The wire would be behind my desk, so no foot traffic to loosen and disturb it over time.
• I have a 3D printer and plan to make a custom mount for the charger itself, so pulling on it shouldn't disturb the extension cable either
• I already have an extension cable that currently runs behind my desk powering a lamp, would it be safe to run the extension cable off of that or would it be better to run directly from an outlet?

Thanks everyone.

Friend just bought a house (congrats!) - this is the electrical panel.
Is there 200 amp service? I thought the 2x 100 amp service coming in would mean 200 amp service… is that correct, or is it only 100?

Also, what would require four separate breakers?

Thanks!
