Do you need a grounding rod at a subpanel on a detached building?

Yes. The panel must be grounded with its own grounding rod. The ground will not be provided with the feeders to the panel, these will only contain your phase wires and neutral. Also make sure that any subpanel installed does not have the neutral bonded to ground. This should only be done at the main panel where the electrical utility service is connected.

How do you ground a 200 amp service with no water main?
You need two forms of grounding according to the code. Grounding to the water main is typically the best ground in a building. If you don't have a water meter you can add an extra ground rod.
How do you Ground a 3 wire service?
If you do not have a underground metal water pipe coming into the building then you put a ground rod at least 2 feet from the buildingf into the ground attach one end of the wire to ground rod run your ground wire and attach the other end to the neautral bar in the panel box. You need special transformer called as grounding transformer for this purpose. Grounding transformer is basically Wye-Delta type transformer with Wye connected winding connected to 3 line wires and derived neutral from Wye side grounded through desired grounding device. Delta side winding of grounding transformer is kept at no load.
What gauge wire to use for a sub panel?
That would depend upon how many amps will be used in the sub-panel. For example, a 30-A subpanel would need a minimum of 10 AWG feeder conductors.
Why does your grounding meter read OL from gen to 1st ground rod and from 1st to 2nd ground rod get 28.51 ohms?
Code requires that the resistance between the two grounding electrodes be 25 ohms or less. You don't mention how deep they are or how far apart they are. THat will make a difference. Or it could be the soil they are in.You need to get the resistance down
What wire size is need in a detached garage that will have a 15 amp table saw?
I would use 3/12 to take care of that, connecting one line for tools and the other for lighting.
How many breakers can be put in a 50 Amp subpanel?
As many as you need. Just make sure the main breaker of the subpanel stays below 50 amps (the rating of the subpanel) and the input to the subpanel, whichever is lower.

How do you wire a storage building?
First, there is not enough information to answer this question properly. What are the specifics? Is this an ATTACHED or DETACHED building? Where is the service or power entrance? Is it at the building or will you need to bring the power from another building or service? What kind of power do you need to distribute, 110, 208, 277, 480? Will it be single phase or three phase? How much power will you need, (in amps) 15a, 20a, 30a, 60a, 100a or more? How many circuits will you need? Where will the circuit and building service disconnects be located? What size conductors will you need? Is this a metal building? If so, additional bonding and grounding requirements are likely. You may need a qualified electrician to answer some or all of these questions. After these questions have been answered, go to your local building official and see if a permit will be required. Next, if you are allowed to wire the building yourself, make sure that you know what you are doing. Electricity is easy to install, easier to install wrong, and causes damage to include building fires, physical injury or possibly even death. This may sound alarmist of me
How do you connect the wires for a 200 amp sub panel to a 200 amp main panel?
Assuming garage is detached less than 80 ft away. You need a 60 AMP double pole breaker for the 200 AMP house panel, and need to have two spare slots. Additionally you should have conduit in running in ground, and have #4/3 W/ground Stranded cable running to the sub panel. This setup will allow for 110V's and a 220V circuit. Connect the two hots, Red/Black to the Breaker on your servicing the panel. Connect the neutral (White) to the Neutral bus bar along with the Ground wire. Sub panel on detached Garage. Attach the White neutral wire to the Neutral ground bar. Attach the ground to the ground bar on the Sub panel. Pull the permits and have it inspected! If your house has the wires from the meter going straight into your panel box then you tie the neutral and ground to the same busbar. However; If you havve a disconnect on the outside of your house then you must separate the neutral andground inside the 200 amp panel box. This is usually prevalent on a mobile home or any time the pnel box you are using is fed from another panel or disconnect.
Do you need a certificate of occupancy for a detached garage in New York State?
not unless the detached garage is on a different parcel than the main dwelling
Do light fittings need to be earthed?
Normally the fixtures come with a grounding screw that you attach the grounding wire to. If the box you attaching the fixture to is metal and there is no grounding wire present then the grounded conduit should ground you fixture.
What kind of regulations apply to smoking shelters?
The biggest regulation that applies pertains to the amount of enclosure of the structure. Smoking shelters for public use cannot be more than 50% closed in by walls or other boundaries. If the structure is detached from the main building, you probably don't need a building permit.
How do you ground a computer?
Grounding an electrical or electronics device commonly refers connecting it's power inlet ground pin to the ground connection of the power outlet. The power outlet ground connects to the ground connection provided by the electricity utility company or the building's common ground connection. The grounding essentially provides a zero volt reference. Many systems which have a metal chassis provide specific grounding points with screws/nuts to connect grounding wire. To ground chassis of a computer one need to connect ground wire to the metal case.
What grounging system do you need on your new house?
You need a grounding system that follows the local electrical code.
How do you wire into the main power supply when installing a 50 amp electrical box for a small shop?
Ideally you need two open breaker locations adjacent to each other. Install a 2-pole breaker to supply 120/240 volts. Rating of breaker should 50 A to subpanel. Do not bond neutral and ground in the subpanel.
How do you hook up a 15 amp breaker to a 60 amp box?
If by "60 amp box" you mean a 60-amp service panel (circuit breakers or fuses), you would generally get a 60-A panel that has several slots designed to accept a variety of compatible breakers, from 15A to 60A. If you have a "box" with no breakers, you would need another "subpanel", with wires from the 60A box to the new subpanel, and install one or more 15A breakers in the subpanel. If you don't need more than one breaker, you might also simply use a 15A disconnect panel with a single breaker in it.
Does grounding your child help the situation?
While children need some type of discipline and/or direction, grounding is rarely very effective. Depending upon the child's personality, grounding will either scare them or make them rebel but never gives them the tools to make better decisions.
