What size conductors are needed to run a 400 foot residential underground electric service?
Need to know what size service is going to be installed at the end of the run.
What size wire do you need for a 100amp braker?
Service entrance wire should be AWG #3 copper.
What is the minimum size neutral for three sets of parallel 500kcm copper conductors for a service?
On large service entrance services the neutral can be reduced. The amperage of the service and the voltage of the service and the insulation factor of the 500 MCM conductors need to be stated to answer this question correctly.
What size USE wire is needed for 200 amps?
As a service entrance wire you need AWG # 3/0 gauge copper.
What wire size for 400 amp service neutral size?
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
How do you calculate the size fuse box do you need for your house?
Work out the number of circuits that would will need - each circuit needs a fuze.
What size wire for 200 amp service with a 60 foot run?
This can't be answered without knowing the voltage, and ground is not the same as neutral, in AC circuits, which I'm assuming this is.
What size ground do you need for 4000 amp service?
500 mcm
What size conductors are needed to run a 400 foot residential underground electric service?
Need to know what size service is going to be installed at the end of the run.
What size wire do you need for 100 amp service if you use alunimum?
2AWG.
What size wire for neutral in a 240v 30 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.
What determines the size of service entrance equipment and number of branch circuits used in a residential home?
Electricians use a service entrance calculation to figure what size entrance to use. There are computer generated programs that you input all the information on the home such as rooms and sizes then it will give you the size, then this is checked against the local codes officer to make sure they agree with the service. The old fashioned way can be done but the program is faster. So all the rooms, and sizes and equipment that are in a home determine what size is to be used. Although computer programs may be faster, you would still be required to know how to do these calculations yourself on a licensing exam. Load calculations are based on the square footage of a building and type of occupancy, plus special loads added to that. You must follow the current version of the National Electrical Code: Article 220 Branch Circuit, Feeder, and Service Calculations. Article 210 Branch Circuits give requirements for the number of branch circuits.
What size jersey did Walter Payton wear?
Fifty
What is hundred and fifty times the size of 10?
five
What size wire to ground water pipe?
For a 200amp service you need number 4 copper
What size subpanel do you need for 6 20A circuits?
The size of the sub-panel is dependant upon the total load amps of the devices you want to connect. Take into account if more that one device will be or could be running at one time.
Breaker box is full?
You have two options, one is a complete service change. The average house service these days is 200 amps 42 circuits. The second option is to install a sub panel off the existing service. Depending on how many circuits you need will govern the size the sub panel. Here is where it gets tricky. Two side by side single pole breakers or one two pole breaker will have to be removed from the original service panel and replaced with a new two pole breaker. The size of this breaker will be governed by the total load of the new sub panel. The wire from the new sub panel to the two pole breaker is also governed by the load of the sub panel. As an electrician I would recommend that you not do it yourself but get a qualified electrician to do it for you. He would (should) take a permit out for the job and get it inspected.
