Is this a firehazard?

So my stepmom was bitchin about having my pc and space heater on the same outlet is a fire hazard, the issue is, the wires are rated for 120v 20a, which is 2400w, and my pc, monitor, speakers, and light take no more then 350 watts max, while the heater is 1200w, 1200+350 is 1550, which is almost 1000w under the max, is it a firehazard or is my stepmom tweakin

Car Display all Faded

Car Display all Faded

Can someone help me with this problem my screen is like faded been like this for a year now as I don’t know what’s causing it.

i’m too cheap to bring it in to a mechanic for diagnostics because I mostly do all my repairs as I am pretty handy.

Before the whole screen went out like this, before it would only be half of the screen literally split down in the middle and one half is normal the other was faded.

Other times there would be streaks of white faded lines from left to right in rows.

I don’t think the weather mattered too much as it’s like this in the summer and winter. Any ideas?

Hi, kinda new to electronics with signals, and I need help with a diy project.

So i have an s21 ultra that i want to mod for better receiving capability aka soldering a different antenna, I have experience with soldering but not with antennas. Here is my questions:

1)is a bigger antenna better? And I mean is if the bigger the antenna the better?

  1. would I be better off with buying a ready made antenna and discombobulating the antenna or building an omnidirectional antenna at home?

3)if you have a detailed pdf with the s21 ultra's components and schematics can you dm it to me or post a link?

  1. do you have any tips or pointers you can give me?

Ceiling fan box

Ohio USA. Very old house, purchased a few years ago after a Reno. Ceiling fan + light combo went dead a few months ago and just getting around to fixing. Replacing with a new fan + light combo with a remote control, so no longer need the dimmer switch. Opened up box and it’s a mess, from my understanding both the switch and the dimmer were hooked up to the fan but could never really tell. I have another switch to replace the dimmer, but not sure if I need to change any of the wiring around in here. Thank you in advance for any help/advice, can send more pics if needed!

Space Heater for bedroom

My windows are old, and it is very cold in my bedroom. The radiator does not provide enough heat to counter the cold. Which space heaters do you recommend for my bedroom?

Two dimmers in series?

I have 2 kinds of lights on my Christmas tree. All are simple dimmable lights with no controller circuitry. Let's call them A and B.

Right now I've got A on a smart dimmer and B on a dumb dimmer. I could put them all on the smart dimmer and stop using the dumb dimmer, except that leaves B brighter than desired.

Can I put the dumb dimmer (with B lights as it's load) and A lights all on the smart dimmer?

I'm well within the wattage specs so that's not my concern at all. My only question is whether or not it's safe to have dimmers in series like that. And of course the dumb dimmer is downstream of the smart dimmer, so that I'm never dimming an electronic controller of any kind.

Bad breaker?

I have a 4 way switch at the tops of my stairs leading to the basement of my house and other switches in the basement obviously. When I turn the breaker off, the lights shut off for a split second then turn back on, but are dimmer. Switches still work and everything. They’re just more delayed.

Then, I flip the main circuit breaker to my panel and all lights in the house turn off but those lights. Again, they shut off for a second but turn right back on, just a bit dimmer. And again, the switches still work and everything. They’re just more delayed.

Any ideas what’s going on?

Add Electrical Outlet in Garage

Hello, good day all. I have a small one-car garage (18ft x 14 ft, approx). As can be seen below (A on the right), there is only 1 GFCI outlet, with two receptacles (which connect our 2 freezers).

https://preview.redd.it/qbqiox3r7g8e1.jpg?width=1614&format=pjpg&auto=webp&s=9702fc29aa86724d82c771f1fccedd2481ddc4ee

I need two outlets on either side of the garage (B & C):

B: The outlet in B will be used for appliances like the deep fryer currently stationed there (or an air fryer).
C: The outlet in C will be used to charge and operate my power tools.

My initial plan is to tap into and extend a line from A to B and then from B to C (across the ceiling). I am not sure if this extension would be advisable. I am concerned that the 20A circuit may be unable to handle the load: two deep freezers, an appliance, and a power tool (assuming someone accidentally plugs in all 4 devices at the same time).

What other options do I have? There is a powder room near the entrance from the garage - with a GFCI outlet. Can I tap power from there? Or better still, just create a new circuit from the breaker panel?

Thanks so much for your assistance.

Have a good day! cY

Advice please!

Hello everyone! I’m not an electrician but I play one on TV.

I’m in the US and I have a series of outlets between two bedrooms on one breaker. None of the outlets work however the breaker isn’t tripped.

So far I’ve done the following:

Replace the breaker itself: this restored power for about 30-45 minutes before kicking off, new breaker still isn’t tripped. I’ve verified that the breaker functions to send or cut power at the panel.

I’ve checked all outlets that I know of for loose wires, none are backstabbed and each outlet is pigtailed off. What I’ve found is some nuts that I’ve tightened, as well as checked the wire nuts. Still no power when flipping the breaker.

I tightened the neutral and ground wires in the panel itself.

I have a toner I’m still learning how to use and when trying to connect it to the neutral and hot wires of an outlet, or ground and hot of the same outlet, it shows a short, but my multimeter doesn’t show continuity when testing the same outlet.

All loads are unplugged from the outlets in the affected areas.

It may be simple it may not be, any suggestions would be appreciated!

US to Ireland adaptor question

Hello I will be travelling to Ireland from the US and are looking for Adaptors. I can across one adaptor that has two inputs 1 grounded outlet and 1 non-grounded, but I read that non-grounded outlets are not safe? But it has two inputs which would make it convenient as it would allow to plug in two devices at once, I’m just concerned about the safety. If someone could please help on this, the product shows that it is fully grounded though but it still has that one non-grounded outlet. I’m confused if someone could please help that would be great!

Voltage high at outlets/switches

I'm not an electrician, but comfortable doing things like replacing outlets, switches, existing fixtures, etc. I always turn off the breaker and check what I'm working on with a multimeter, so I know the voltage has always been in the normal range for everything I've touched both before and after.

I was going to replace a light switch today and noticed the voltage was 143V. I checked the outlets on that circuit with the same result. Then I checked around the house on different circuits, and the voltage gets as high as 153V in some locations. What could be causing this?

I cut the rectifier of my Christmas lights and caused a short, any way to fix them?

Hey guys, I was stupid to think I could connect two different types of Christmas lights together, one of them had a rectifier at the end to which you could plug another series, but my other lights had just a normal plug, so I cut just before the rectifier and after the plug and combined them together which of coursed caused a short. After that I disconnected the wires and isolated the wires ln the first set of lights (where the rectifier used to be) and again it’s causing a short which trips my breaker. My question is if I solder the rectifier back would that help or they are probably all blown from the short and now there is voltage overload? I saw somewhere that you should solder the wires together if you remove the rectifier but that doesn’t sound right lol

testing the new led bars on my philips boombox and its perfect now. Since it only runs on either those old big C-batteries or wall power, I fixed it by installing a step up converter inside and a 30000mAh power bank on the outside👹 Plays for 35 hours straight on ONE charge🔥🔥🔥🔥

Do I Need An New Outlet Added?

Under sink has a single outlet and currently have a disposal and a Moen faucet plugged in. I will be adding an on demand water heater there as well and I am short one place to plug in. Will I need to add an additional outlet, or will an extender work for these items? Obviously want to be safe, but don’t want to over do it if not needed.
