By asking this question you are probably not quite ready to take on this particular task. You may or may not get lucky and receive some information in an answer here! If you hope to get enough information on this site to be able to do this job properly and safely, please do not rely on getting accurate information about such a potentially dangerous subject. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you put just one wire in the wrong place you risk being killed by electrocution or you could even start a house fire.
How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact locations of the main service entry point and any outlets you wish to install. If they are anywhere subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you don't want to go to your local library or bookstore - to find and read some books about electrical wiring and appliances and how to install them safely, and to find out about your local Wiring Codes and Regulations - then the best advice anyone should give to you is to call a licensed electrician either to do the job for you or to advise you what you may be allowed to do yourself. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
For Service Entrance Cable 600 kcmill (Thousands of circular mils).
Look on the handle end of the main breaker. There should be a number there. That is the amperage of the main breaker. That is the size of your house service.
Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
The maximum current capacity of a 100 amp service panel is 100 amps.
Yes, a 100 amp main panel can have 2 separate 50 amp circuits protected by 50 amp breakers. This configuration allows for two separate circuits drawing up to 50 amps each from the main panel without overloading the panel's 100 amp capacity.
The maximum amperage capacity of a 100 amp panel with a main breaker is 100 amps.
A 100 amp service provides less electrical capacity than a 200 amp service for a residential electrical system. This means that a 200 amp service can handle more electrical load and is better suited for larger homes or homes with higher electricity needs.
The maximum amperage capacity of the main breaker in a 100 amp sub panel with a main breaker is 100 amps.
A 100 amp service will supply your electrical current needs UP TO 100 amps.When doing load calculations on a 100 amp panel it can only be loaded up to 80 amps.
For a 100 amp main panel located 100 feet away, it is recommended to use a 2/0 copper or 4/0 aluminum service cable to ensure proper voltage drop and capacity for the distance. Consult with a licensed electrician to determine the specific requirements based on local codes and conditions.
Yes as long as the combined current from both doesn't exceed the limit of the main.
For a 100 amp service in copper, a wire size of 3/0 AWG should be used.
The maximum amperage capacity of a 100 amp main breaker in an electrical panel is 100 amps.
No, each size service needs its own meter base.
