DANGER!!! This sounds like a ground fault. They are particularly dangerous if you get wet, which is why Ground Fault Circuit Interrupters have been required for many years in kitchens and bathrooms, among other places. If you have shoes on, you are insulated from the floor. Without shoes, a little bit of electricity makes its way from the fan through you to ...

It's dangerous. You've spotted one important flaw but it can combine with others to make a really dangerous product. I originally suspected it was made in Europe by someone with more interest/knowledge in the sculptural aspect than the electrical one, but I've since spotted contact details in China for the seller. Either way it shouldn't be sold. Here's why ...

I'm not certain what guage that wire is but many manufacturers will cite a minimum bend radius. It may or may not be code compliance wherever you are in the world. I suspect that wire has a minimum bend radius between 1 and 2 inches. You can achieve that most easily by just rotating the receptacle. The wire will tail upwards, which will look strange, but it ...

I do a lot of work on older homes and see stuff like this all the time. Keep in mind that the equipment grounding conductor (EGC), that bare safety ground, was not always present in wiring systems. If you see old homes - a little older than this one - with two-prong receptacles, those were wired back before the EGC was part of the system. I think when ...

The safety solution is to either add a grounding using a grounded cord with the ground branching off and attaching to the metal as close to where it enters as possible. Or you can convert the lamp to low voltage LED with the 220 to 5 or 12V conversion external to it so safety ground isn't a requirement.

It doesn't need to be a GFCI outlet. It needs to be GFCI protected. GFCI protection is conferred by having any particular outlet obtain power power from the LOAD side of a GFCI device somewhere. On most string-topology circuits, a single well-placed GFCI device will protect the whole circuit. If you stick a GFCI tester in there, push the button and the ...

You should trim the extra copper off it will not help to have it hanging out there. You also need to make sure when you put things back together the clamp is on the covering for the cable not the individual wires but other than those items I would say it looks safe. A proper torque would be needed to be 100%.

Looks more like mildew, which is related to mold, but not as dangerous (from a health standpoint). Yes, a dehumidifier could help prevent mildew. I would also look for sources of the moisture, e.g. a clothes dryer that is not venting to the outside, a bathroom vent that is not functioning (or non-existent), water leaking somewhere etc.

Your pull chain switch is probably starting to fail. The switch and chain wouldn't be grounded because it in a plastic housing so if the switch contacts are leaking over to the chain, that's where your shock is probably coming from.

Some metal products may contain elements or chemicals known to the State of California to cause cancer, birth defects or reproductive harm. Like nickel, molybdenum, lead, chrome, etc. I would imagine that the file manufacturer labels the product out of an abundance of caution so they never have to worry about being sued or prosecuted, even if the materials ...

Leaning the ladder against the gutter If the gutters are safe to lean on, and if there are no potential problems with denting them, then that is the way to do it. The ladder will be stable and you will be in a better position for cleaning the gutters than if you were on a ladder leaning on the walls. Some gutters are actually strong enough that you can ...

I think mark f has already answered your question well. I just wanted to add some photos from a similar project I did last year in case these are helpful to you. I installed a weatherproof cover and box to replace the old ones that supplied my above-ground pool. Fair warning: don't do this at your own pool because my installation was deficient in several ...

The UPS battery won't be backfeeding into the house service. DC current won't be flowing back through the rectifier diode. I'd be more concerned about doing something wrong with your switch replacements, turning on the power and frying your UPS board. We see this happening all the time here. Play it save and unplug the UPS and anything else on the circuit ...

DANGER, WILL ROBINSON The glass doesn't stop the microwaves. The mesh does. However, without that glass in place, the chance of something else going wrong - e.g., that foil coming off or some other part coming loose, is drastically increased. As far as replacing with plastic, I definitely don't recommend it. I'm not against plastic for certain repairs - e.g.,...

While this should be acceptable, I have personally found a UPS which backfed 240AV out its input pins. I only found this out when brushing against the exposed pins on the wall plug - That UPS went straight in the junk pile! In short, when dealing with mains power, make no assumptions. Use a non-contact voltage indicator or a plug-in lamp or even a ...

I would suggest an update to a extra duty double gang cover. Extra duty or “in use” covers are made to be used while something is plugged in. Taymac mx6200 is a cover that has 55 configurations made by Hubbell this will replace your existing cover and it has switch plates and receptacle plates that snap in so your configuration is what you need. This is a ...

TL;DR If using the product can release the chemical then slap a sticker on it. I think it's just an overzealous interpretation of: Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that ...

We're reading tea leaves here to guess at NFPA's intent. NFPA writes the "model electrical code" which they offer for anyone in the world to adopt as their law. But politically, NFPA has been having a big problem. Normally NEC changes are fairly trivial in cost: Pull a neutral wire on switch loops, gosh, you're using the /3 Romex instead of the /2. It'...

NEC doesn't require AFCI because it does require GFCI, and they are not the same. GFCI outlets protect against electrical shock and this is very important around water. AFCI protects against electrical arcs that come from damaged cords and bad connections. Arcing is super hot, and is responsible for electrical fires. A combination protection device could ...

Yes - examples are out there. For practical reasons the chimney tends to be metal, or in older buildings, just a smokehole in the roof.

Generally, it's safe to be in an attic with fiberglass insulation without a mask. Is it a good idea? No. It can get into your lungs and cause the coughing you're experiencing and can also irritate your throat. the coughing you're experiencing is probably a combination of the fiberglass and the dust that settles from the venting of the attic. Do yourself a ...

No, that is not safe. The 23W CFL limit means that you should not use a bulb that uses more than 23W of power. A 30/50/150W 3-way will use more than that on its lowest setting. If you don't want to use a CFL, and I don't blame you, please consider an LED bulb. These generate even less heat than a CFL. Use the ACTUAL power rating, which is likely to be in ...

Because of the things you'll be filing with it The same reason sandpaper and other paint-prep supplies contain warnings of lead. The sandpaper doesn't contain lead; but good chance what you're sanding does. To be more specific, you're referring to the text of a Prop 65 warning, presumably text out of 27 CCR 25603(a) affixed to the product package per 25602(...

Metals Depending on the alloy, tool steel probably contains cobalt and/or nickel. These are listed on Prop 65. Cobalt: Cobalt metal powder Cobalt oxide Nickel: Nickel (Metallic) Nickel compounds (due to the ambiguity in this line, anything with nickel) Nickel oxide Additionally, there are other metal compounds of chromium, vanadium and even iron that ...

Correct. GFCI is actually the ideal solution for the people problem (shocking people) and serves that purpose better than grounding. Assuming no boneheaded bootlegging of grounds. But GFCI (alone) does nothing for the ESD/lightning problem which can damage sensitive electronics or cause goofy problems with radio transmitters. Current travels in loops....

The ladder should be placed against the gutter and extended (3' or so) above it, so you can do your work without reaching up blindly. Doing the work as you suggest could cause you to have an unstable body position, reaching up and over like that. If you are concerned about damaging the gutter, you could fasten a wide softner of some sort to the ladder. If ...

Chances are the ceiling is damp and you'll be fine. However, I have never been a fan of water and electricity at the same time. With the breaker switched off, take the globe, glass off the fixture. Water probably wouldn't be in the junction box but could have dripped between the box and the ceiling. If there is any dampness, dry everything off. Put the ...

Don't Replace, ADD Removing the screws is a lot of extra work, for no real benefit. In fact, you might even find that some of the old drywall screws snap when you try to unscrew them, and then you have no practical choice but to add other screws anyway, leaving the partial screws in the studs. Just add proper cabinet screws. Depending on the layout, you ...

You don't need a license to operate a plumbing torch. There's no danger of it spontaneously exploding if you keep it away from heat sources and open flames. He hasn't dealt with you punctually because he's an unreliable flake. Look up laws for abandoned property in your locality. Eventually his tools become your tools.

Replace the existing cover (and switch plate) with a new two gang outdoor cover such as one like this: The new cover seals against the existing outdoor rated handy box via a weather seal. You will likely need to put a new cover plate over the switch as well. And be sure the Outlet or entire Circuit is GFCI protected since its outside.
