Good to know, luckily no dimmers here but I may do some on the main level eventually

2017-07-26 21:34:07 UTC

Anyone ever make an alternator?

2017-07-26 21:34:51 UTC

That is, convert physical energy into electrical?

2017-07-26 21:48:22 UTC

It is not the easiest thing to do. You basically have a motor that is working backwards. You have to have quite a bit of copper windings inside the frame and you would have to spein it very quickly. If you had it attached to a bicycle or other of means it would not be so bad

2017-07-26 21:48:55 UTC

Electric lady would not be that difficult to build the difficult part is when you have to do the spinning!

2017-07-26 21:49:20 UTC

Seen them on sail boats. Was also thinking sewing table pedal.

2017-07-26 22:10:39 UTC

Yes you have to get the ratios in the windings right and then have a set RPM to keep the voltage at a set level. I'm sure there are simple units I'm talking more along the lines of a consistent voltage output of 110v or higher

2017-07-26 22:11:52 UTC

Any way to do it without copper? Practically I mean.

2017-07-26 22:15:34 UTC

The two components of a motor or generator do not actually touch. It works off what is called induction. Copper or gold would give the best results. Some type of metal has to be used other metals do not work as well

2017-07-26 22:18:58 UTC

Yeah is it basically a spinning core inside of coils?

2017-07-26 22:27:37 UTC

Rotor and stator

2017-07-26 22:30:12 UTC

Yes sir and giving what you're trying to do using steel or something of that nature just wouldn't work for the induction

2017-07-26 22:30:18 UTC

Keep in mind when building this that it will always take more energy to make energy than the energy produced. Heat and friction are energy losses

This is the equation that prevents perpetual motion

2017-07-26 23:10:27 UTC

Ugh im at a negro house giving an estimate

2017-07-26 23:10:55 UTC

Literally a chimp out on tv..... and the smell....

2017-07-26 23:11:17 UTC

slave art?

2017-07-27 00:04:58 UTC

Hahaha

2017-07-31 13:36:07 UTC

@Lebens What is a "R&R commercial 225A single phase panel?"

2017-07-31 17:16:04 UTC

Remove and replace a 225A single phase panel

2017-07-31 17:38:44 UTC

Ah ty

2017-08-01 02:07:28 UTC

@Lebens so you basically disconnected all the wires from the old panel, tracked them, and required them to the new panel?

2017-08-01 02:08:00 UTC

How long does that take?

2017-08-01 02:08:38 UTC

Im on my 10th hour

2017-08-01 02:08:53 UTC

Still not done

2017-08-01 02:09:04 UTC

Tomorrow i have another one to do

2017-08-01 02:09:08 UTC

Holy feck

2017-08-01 02:09:22 UTC

Wednesday im installing a lighting control system

2017-08-01 02:09:49 UTC

2.5 days work and ill clear \$6k

Contractor life

2017-08-01 02:11:02 UTC

That's awesome.

2017-08-01 02:22:48 UTC

@Lebens that panel/meter combo in that last picture is the second one of those I've seen you post. It's similar to what I would call a meter bank for a multi dwelling bldg. Is that something that is common for your area. Is that what the utility requires? I'm in Louisville and all of the services that we install have a meter Base outside and then a panel beneath it or just inside the wall from it. I was just wondering if that is something that you personally prefer or is that something that is common to your neck of the woods

2017-08-01 02:36:42 UTC

@Deleted User east coast vs west coast. Out here we use all in one enclosures, i hate it. You guys have the better version

2017-08-01 02:39:29 UTC

@Deleted User this building wanted a way to work on the panel without shutting down the substation also. With the meter socket they can monitor usage and have a means of disconnect for swapping main breaker

2017-08-07 18:38:14 UTC

I was getting ready to run an outlet off this existing outlet. First tree ground wasn't connected and three was a jumper you can see in the pic. It's this normal practice. I've never seen it before.

2017-08-07 18:43:20 UTC

It looks like the wiring was a two wire system. For a while they decided that grounds were necessary and did not pull a ground conductor. The neutral wire which is the white wire is at Ground potential in the panel so basically it is grounded just like a ground wire would be so they are putting a jumper between the neutral screw and the ground screw so as to ground the outlet. This is not cold legal. The proper fix would be to go buy a two wire Outlet which is an outlet that has the two vertical slots but no round ground hole and put that back in. People change and put 3 wire outlets on so they can plug things like plug strips and other devices with ground prongs but it is neither safe nor legal. If there is a green or bare ground conductor in the box then you can use that to bond to the green screw and use a 3 prong outlet otherwise it should go back to the old to wire original scenario

* unnecessary

2017-08-07 18:45:52 UTC

I see this all the time and it is a scenario that will work and provide both a neutral and a ground but like I said as per your electrical code there should be a wire for the hot a wire for the neutral and a wire for the ground.
