![]() If you need to run the cable longer than 200 feet, you may have to go with the larger-sized wires. However, if you want to cut costs, you can choose a smaller-sized neutral wire for your service. Typical neutral wires are used for internal wiring. However, it should be thicker than the phase wires. In residential 200 amp service, the neutral wire should be no smaller than the phase wires. The bigger the load is on the circuit, the larger the voltage drop. Both copper and aluminum wires have the same voltage drop, but the difference is only 3%. Copper wire is generally more durable than aluminum. Copper wire has a higher conductivity rating and is used over longer distances. The aluminum wire has lower conductivity and heat resistance. ![]() Here are some guidelines for wiring a 200 amp service:Ĭopper and aluminum wires both have 200 amp service ratings. The neutral wire acts as the central hub for multiple loads and needs to be large enough to pass the total load. If they are not, they could short-circuit, causing fire and electrocution. Does neutral wire need to be same size?īuilding codes state that the hot and neutral wires must be the same size. The minimum size for copper-clad aluminum for a 200-amp service is #4/0. In addition to copper’s benefits, it’s also a good conductor. ![]() Another plus is that it doesn’t require an antioxidant coating on the power terminal. Although this material is cheaper than pure copper, it has the advantage of being much more durable. This material offers some of the benefits of copper and aluminum without the price. The size of copper neutral wire required for a 200-amp service is typically #2/0. When running a ground wire, consider the type of insulation it has. A larger gauge compensates for the increased resistance of a smaller wire. A shorter wire may not be as dangerous as a longer one, but the higher the distance, the higher the gauge. You may be wondering: “What size copper neutral wire do I need for securing my 200 amp service?” There are several factors to consider when choosing wire. What size copper neutral do I need for a 200 amp service? Copper wires should be 16 mm in diameter, while aluminum wires should be 25 mm in diameter. If you have more than one circuit in your house, you’ll want to use a larger neutral wire to avoid short-circuiting. The size of a neutral wire is largely determined by the size of the other wires in your system. You should use a sized neutral wire to avoid short-circuiting. Copper wire is also more expensive than aluminum, but it offers good conductivity and won’t corrode. ![]() Copper is better at conducting electricity than aluminum, so you may want to consider copper-clad aluminum or copper wire with a special copper fitting on one end. Generally, you should use #3/0 copper wire for a 200-amp service. If you’re looking to install a new electrical service, you should know how to determine what size neutral wire you need. What size neutral wire do you need for a 200 amp service? In the event that you’re using a 220/120 vac appliance, the size of your neutral should be smaller. The size of your neutral wire should be about the same size as your hot wire. In the US, the standard for electrical wiring is the American Wire Gauge, and the size of your 200-amp service requires #4/0 copper or aluminum-clad wire. The size of the neutral wire depends on the type of electrical wiring in your home. For this reason, you can use a smaller neutral wire size than a larger one. In residences, the unbalanced load is usually minimal. In addition to its size, the neutral wire should be able to carry table 16-A bond and unbalanced load. Typical residential services can use #6 copper, but you should ensure that it is at least #4 copper. The size of your neutral wire will depend on the amount of load that your home is using.
