What kind of help do you need? If you want to troubleshoot this problem what knowledge and tools do you have to work on electrical wiring? If there is a transformer, then you must have low voltage...
-
It is a low voltage transformer, with anywhere from 6 to 24 volt output, probably provides voltage for your doorbell.

An open ground test at a receptacle means that circuit has an open ground between the receptacle and the panel. You may not have a ground rod, althou there should be at least one, your system may be...

Need to know more details as to why you believe this needs to be done. Grounding of a service is simple and should had been done by the installer. Just arbitrarily connecting a grounding electrode...
-
Usually a blue test button on the front of each breaker, depending on the brand. During a power failure, oft times it is not a clean break, so to speak, could be something weird happened at the place...
-
Any chance the tripped breakers are Arc Fault type? Some times a power failure can cause voltage surges that cause breakers to trip. There are devices on the grid call Reclosers, for example, if a...

No additional GFI devices are needed as long as the new receptacles are GFI protected by the interior device.
-
Some photos of the fixture would be helpful.
-
Are all the lights working? What happens if one breaker is turned off, then the other is turned off? Exactly which slots are the breaker located in the panel?
-
So the electrician that installed it violated two codes, did not attach to the structure, and left it with no cover? If you see surface rust, then there is corrosion inside the receptacle, and needs...
-
That fact does not matter. All grounding must be done at the first Main Disconnect.
-
No, since the Main Breaker is at the pole, the feeder must be 4 wire to the home, for the two hots, one neutral and one equipment ground, with the ground rod driven at the pole grounding both the...

There are literally hundreds of styles of micro-switches available. If you were to look thru:...
-
Which one of the four choices was discussed in the class?
-
Either the new button is defective, or you got the wrong button which is now a closed switch until pressed.

The A15 and the A19 number is the designation of the bulb size, not the medium base. Bases or socket numbers begin with "E". The diameter of lamps is measured in 1/18ths of an inch, so the A15 lamp...

This is not true, first see Section 404.9(B) above.
Second, there are two types of switches available, if self grounding, then no equipment ground is needed:
1221-2 > Toggle > AC Switches >...

Stan, can you review 404.9 (B)?
Section 404.9 (B) Grounding. Snap switches, including dimmer and similar control switches, shall be connected to an equipment grounding conductor
The above...

They only hold the screws onto the device. Removing them have no affect on grounding.

You would be best contacting Nutone directly to learn what they have as a replacement.

Each phase can handle 200 amps.
-
36 inches assuming it is opposite an insulated surface.
42 inches if opposite a grounded surface, (ie: concrete wall)
48 inches if opposite other switchgear.

Don, the title of the post is 480v 3p panel , I do not think this is residential.
-
Will not hurt to give it a try.
-
If a fluid line needs to be above a panel in the dedicated space above the panel, a drip pan is allowed to be installed below the piping and above the panel to protect the panel.
-
Often, the action of turning on a switch can cause a AFCI breaker to trip, a worn out switch will cause excessive arcing in the switch.
Replace switch.

In addition to needing more details, you need to re-word your question.
The way I read:
what size of wire guage do I need to fuse a 200A gear switch
Sounds like you want to use a wire as a...
-
A feeder conduit can contain wiring from other branch circuits, conduit just needs to be large enough. The 2" PVC Sch 40 conduit you propose is large enough for the 3 - #1 AL XHHW, 1 - #6 Al XHHW...

Explain to POCO that if the problem is with any of their connections, at the transformer or at your service connection, they are liable for any damage done in your home.
For most POCO, any...

If the switches have a green ground screw, yes, connect each to ground, and connect to the metal box.Do not remove the insulators.
This is all per the National Electric Code, which each state...

DO NOT Use a 40 amp Breaker on 20 amp wiring!
There is no such thing as a 140 amp panel or service.
You are not allowed to do your own electrical work in any building that is not your own...
-
And the problem was solved:
-
Most, if not all, homes have 120/240 volts in the service.
What you need is to hire an electrician to check the amp size of the service, and confirm the service has sufficient amp capacity to...
-
I moved this to the correct forum.
The difference between a 100 amp service and a 150 amp service is 50 amps additional capacity on the 150 amp service. I am sure you knew that already, and I...

Any "friend" that wants you to "show" something on cam is not a friend. Just someone that wants to get off on seeing whatever you have to show, and wants to degrade and cheapen you.

I merged your two questions. Just enter all information in one question.

If you knew that why did you ask? And now you ask about a 10 kW motor, as if we were suppose to know what you meant?
A 10kW motor will not draw the same lower current of a 2 kw motor.
How do...
-
Since it is obsolete, it cannot be found on the internet, so we do not know the generic details. Can you describe it, where is it installed, perhaps provide a photo?
-
Stan makes a good point, but assuming both motors are drawing nameplate watts, the difference is 1.1kW, and one hour is 1.1 kiloWatt-hour.
Even if the 2.2kW motor was not running at full load, the...
