Why is there a metal sleeve in a plastic junction box?
Replacing a few 3 way switches and noticed this. On one the ground wire contacted this metal sleeve and arced. Im considering removing these sleeves as there is already a plastic junction box. Any idea what they are for or why it would be bad to remove them? The metal boxes are not grounded themselves, this is residential.

Is a resistor needed with outdoor lights
I hope this question isn't too basic. I have a string light outdoor tree that had a bunch of bulbs go out. Replacement bulbs are hard to come by, but I found some on Amazon. However, I discovered that one of the lights (I assume it was the first one in an individual string) has what looks like a resistor. There are 12 strings. I haven't checked but I'm guessing they all have one light with this.

My question is it is safe to replace them with bulbs without resistors or is that creating a fire hazard? I cannot find replacement bulbs with resistors so it's either that, or alternatively I leave the burned out bulb with the resistor at the top of each string and only replace the other bulbs (but does a burned out bulb still serve the purpose?).

Thanks!

This is sus, yeah?
So I am noticing subtle charge on the metal objects interacting with my metal counter and looked underneath to see this, could this be the culprit?

No power in garage - electrician said there’s no ground
Hey all,

Here to get some advice on this electrical issue. I have a garage that had some electrical work “done” several years ago. It’s never worked properly and most of the times, never works. The switches as shown are for lights in the garage and it’s probably turned on once in the year.

Electrician came to look at it and said there’s no ground and it’d be too complicating to put in a ground. Not sure if these photos help at all but are there certain tests that I can do etc (with my multimeter)

Do I have 120 or 240 volts for my garage?
Hello! I’m trying to get a heater for my detached garage. I live in WI, it’s not insulated, and it’s COLD. I’d like to be able to sit in there and enjoy some 420 friendly activities without freezing once in a while. Depending on the heater I get, I need to know what kind of voltage my garage can handle. Could someone help? Here are pictures!

What's up with the different colors and labels
Just sitting in a hospital and I got curious as to why there are 2 different kinds of plugs (I guess). Any of you ever wire a hospital?

Help identifying wire. Do I have 120V?
I’m not sure if this is something I can tap into. I have a whole garage wall with no power and I am trying to run a whole new circuit to two-four boxes along this wall. I was not sure if I already had a like to my breaker, need help identifying this wire

Why is light fixture wired this way?
I was replacing a light fixture and the white wire from the existing fixture was connected to the stripped mid-portion of one of the white wires from the box with a wire nut. The wire from the fixture came out of the wire nut when I unscrewed the fixture, so you can't see it connected in the photo.

Question: Why not wire the white wire from the fixture to the wire nut containing all the other white wires? Why was the wire nut from the existing fixture connected to the mid-point of that single white wire?

Photo 1: arrow points to wire nut on stripped portion of middle of white wire in box (this was connected with white wire on the fixture)

Photo 2: arrow points to the white wire on the fixture that was connected to the middle portion of the wire in photo 1 with the wire nu

Additional 200 amp power
I have a 400 amp 3 phase main electrical panel which service 10 units each of which have 7 x 60 amp panel or 3 x 100 amp panel.

Is it possible to bring in a separate 200 amp power supply to the building for one of the unit which bypassed the main electrical panel and hooked it up to its separate 200 amp electrical panel? - If this is possible, will detached the current 100 amp electrical panel from the existing main panel.

Thanks!
