![]() This is due to the fact that a 200 amp service is designed to provide 160 amps of continuous power, with an additional 40 amps of power available as emergency or emergency back-up power. Generally, the maximum amount of amps you can draw off a 200 amp service panel is 160 amps. The amount of amps you can pull off a 200 amp service can vary depending on the size and type of service you have. How many amps can you pull off a 200 amp service? Furthermore, liquidtight conduit should be used to increase the lifetime of the service and to maintain safety.Īll of these factors will need to be taken into account when determining the maximum distance a 200 amp service can run underground. However, it is important to note that when running any type of underground service, local electrical code requirements will need to be observed. For example, at a voltage of 250/420V, a four-conductor Aluminum 4/0-250MCM underground service rated for 200A could run up to 250 feet in a single length. Generally speaking, 200 amp service is run using Aluminum 4/0-250MCM cables, and the maximum distance it can run will depend upon the voltage, current and material type of the underground service. The distance the service may run and the type and size of underground cable required can vary, depending upon the voltage, amperage and number of conductors necessary. It is possible to run 200 amp service underground, however it depends on a variety of factors. How far can you run 200 amp service underground? Furthermore, the wiring should always be sized according to the latest National Electrical Code (NEC) requirements and must be installed in an approved manner.Īn experienced electrician should be consulted to properly size and install wire for a 200 amp service. ![]() It is important to note that larger wires should always be used for a larger load requirements, as it can help to reduce voltage drops in the circuit. Additionally, if the service is over 150 feet from the breaker panel, then 4/0 AWG wire would be required. Depending on the electrical service entrance, a 200 amp service may also require larger AWG wire in some instances.įor example, if the service drop is greater than 70 feet, then 6 AWG wire would be required. This is the standard size for a home with a 200 amp service. 30 circuit main breaker, as it is for the 200 amp main lug.For a 200 amp service, you will need 4 AWG (electric current or amperage) copper wire. I checked the prices and they are about the same for a 100 amp. Would save the homeowner a little if they want to expand any more. On second thought after reading Curt's post, I might use a 200 amp 30/42 circuit main lug panel just in case in the future the main breaker and feeder needs to be changed, the panel will already be there. This is not the first time I've needed more spaces for a "panel change out". ![]() Lowes or Home Depot in my area don't carry anything over a 20 circuit 100 amp panel, and even the supply houses don't. This will probably be the route I take, if the homeowner want it done. I found out today at one of the supply houses, that they can order me a Seimans 100 amp 30 circuit from about an hours drive from where I live. Normally I wouldn't do it like I mentioned above, but I need more circuits than a 100 amp panel can give me. I don't know if I can get a bigger than 125 amp breaker to fit in the 200 amp panel outside or not. My other option would be to run 125 amp wire maybe and put 125 amp panel that might have barely enough room for the circuits. House belongs a 86 year old man and the panel will be in the basement. In the event that the load does get up to 90 amps or so, the outside breaker would trip, so the 200 amp is just really used as a means of disconnect for the sub panel, which I know is not really necessary since there is a main outside, but just for convenience purposes, I am thinking on putting one if I can. The wire size feeding the old fuse panels is probably #2 as far as I can tell at this point ( wasn't able to identify it completely ) but it is fed from a 90 amp breaker. ![]() The reason I would consider using the 200 amp, is to get the amount of circuits that I need in replacing old fuse panels with one breaker panel. Is there anything in the code that would prohibit using a 200 amp panel with a 200 amp main breaker as a sub panel that is fed by a 90 amp breaker. ![]()
