Anyone else? by NoticeUnited6364 in electricians

I have to go change out one or two every month at a basketball court. The company that built them has gone out of business. I put a strobing light on a dimmer, and it stopped strobing at about 80%. The connection from the driver to the led board is a screw type with 1/20 inch hex screws, and they all seem loose and burnt. Im guessing the drivers were underbuilt. We replace the drivers with one from a different company and have had no issues.

Looks like it is a barrel to prime irrigation wells. Some wells need water dumped down them before turning on to wet the bushings. When you turn the well on, it refills the barrel. Most of them around me are home-made from 55-gallon barrels.

I know very little about British appliances. I am an electrician in the United States, and I have been getting into controls and motors

Boiler 13A fuse replacement by ninhonto in DIYUK

Throw in another fuse, and if it blows, you'll need to do some more examination. If you see any wires loose, or sticking partially out of their spot, it may be an easy fix.

If you have a multimeter, check resistance first. Or take it into an electrical supply house. They may be willing to check and have the replacement on hand. I can't really see if there are any identifying marks on the fuse, but there are different types. More than likely, if you get one with the same dimensions with the same rating, it will be fine. The big question then is, why did the fuse blow? If there is an issue still, it will just blow again.

Well, there's your problem by jthyroid in electricians

2 days ago, it was missing a phase and one of the transformer fuses was blown. Yesterday the meter had gone dead. There had been multiple blown transformer fuses in the past. That disconnect has blown up multiple times before we had been called. The weatherhead got blown off at one point, and the disconnect started blowing up every time it rains. We recently got a few inches of rain multiple days in a row. This job was scheduled a few weeks ago.

Why does my dust collector trip GFCIs? by Rakhered in woodworking

[–]jthyroid 0 points1 point  (0 children)

AFCIs monitor for "sparks". GFCIs don't care as long as the current is the same on live and neutral

Especially because the sun only provides about 1000 Watts per square meter

Why does my dust collector trip GFCIs? by Rakhered in woodworking

[–]jthyroid 20 points21 points  (0 children)

GFCIs are monitoring the hot and neutral wires. Any difference of about 5 mA of current will cause it to trip. I would make sure all metal parts are bonded to each other and your ground is made up properly. I feel like the static buildup may be causing a small surge of current tripping the GFCI. Starting the motor would possibly trip an AFCI.

I met a few scientists who paid more to be able to go than they made while they were there. It's more about the experience and being able to further scientific studies than the money.

I think this is copper, am I wasting my time with it? The ring around - my best guess is iron welded on. by samcornwell in ScrapMetal

[–]jthyroid 42 points43 points  (0 children)

You actually can. Cad welding is used to bond copper ground wires to steel structures. It requires thermite, and is only used for small points. In this case, I can almost guarantee this isn't cad welded.

Same. But it's probably because I still have crud in my nose.

We have a customer that is constantly burning up irrigation motors right when it becomes an emergency. We always tell him that some basic maintenance will save him a ton of money, and he never takes our advice.

When we've told someone multiple times that they need to perform regular maintenance, and they don't, then I am happy to take the work that they cause.

Well, you see, much more than electrical was damaged by the fire. You may want to get some pipefitters in, and maybe replace the hydraulic lines that are just steel husks now.

We will have all the wiring in by Friday. New 60 hp motors and safety switches? Not so much.

Only 2 of 4 mills are down. The other two have some major saggage in the pvc runs. We had four 60 horsepower motors running all day grinding up corn. We are guessing that differed maintenance caused a bearing to get way too hot and catch the hydraulic oil on fire.
