To wire a subpanel, you must know how many circuits the main panel can handle. In most cases, you can add as many as 20. The first step is to figure out the number of subpanels you need. These secondary circuit breakers will feed off your main panel and can handle up to 200 amps. How do you wire a 200 amp sub panel from a 200 ampĪdding a sub panel is an effective way to extend your electrical system beyond the capacity of your service panel. Nevertheless, aluminum wires need to be of higher gauge in order to compensate for the lower conductivity. Aluminum wires, on the other hand, have lower conductivity than copper and are more susceptible to heat and corrosion. Copper wires need to be at least #2/0 in diameter in order to provide the maximum amount of voltage.
#200 amp service wire with ground code
The size of your primary conductor is a guideline for your safety, but local jurisdictions are responsible for establishing the actual code specifications.Ĭopper wires are highly conductive, sturdy, and durable. For this reason, you should check the NEC’s guidelines for grounding wire sizes.
#200 amp service wire with ground install
To install a grounding wire in a 200 amp service, you need a bare copper conductor of four or two AWG, but you may need a larger size depending on the fault current and run length. In residential settings, copper wire is typically used. Grounding conductors must be spaced at least two feet apart. Consumers are encouraged to connect the neutral wire to the larger lug on the neutral buss bar. According to the National Electrical Code, all buildings must have one or more grounding rods. What size ground for 200 amp service-What size ground do I need?Ī basic rule of electrical safety is the installation of a grounding conductor, otherwise known as a ground wire. In any case, make sure to consult a licensed electrician before you install the new service. If copper isn’t available, you can use copper-clad aluminum, or special copper fittings on the ends of the aluminum wire. Copper is better conductor of electricity than aluminum, which may interfere with the flow of electricity. When installing the new service, the length and type of ground wire will determine the size. The length of the grounding rods must be at least four feet. The grounding rod is made of copper, which is a good conductor of electricity. The grounding wire connects the service ground connection to the rod, which is connected to the grounding system. The neutral wire connects to the larger lug on the neutral buss bar. The grounding system is comprised of three wires: hot and neutral. The NEC also specifies minimum conductor sizes. The NEC is a guide to safety, but local municipalities set their own code guidelines. Depending on the length of the wire and the fault current, the size may need to be larger. What size wire do I need for a 200 amp service?Īccording to the National Electrical Code (NEC), a minimum size of ground wire for a 200 amp service is two-inch, four-gauge copper or aluminum. The task can be daunting, so it is important to research local rules and electrical codes thoroughly. In addition, you should get a permit if you are not familiar with electrical work. You should hire an electrician to do this job as local electrical codes will differ. This chart is larger than the AWG chart.ĭepending on your local electrical codes, you can install a 200-amp service with a wire size of #2/0 AWG or #4/0 AWG. If you are not sure what size ground you need for 200 amp service, you can consult the KCMIL chart. You can also use #000 AWG wire, also known as 3/0 AWG. The wire should have at least 250 Amps of ampacity. Generally, the service provider recommends that you use a minimum of a two-foot ground rod. Here are some guidelines for you to follow: Local municipalities are also responsible for determining these guidelines. The amount of fault current may require a larger primary conductor.
