So, the wire run to an outbuilding must be short enough (or big enough) to conduct all of the voltage being sent to it. However, there is enough resistance in any wire to eventually stop conducting electricity altogether if the wire gets long enough. Both offer very little resistance to the flow of electricity, so they are considered conductors, meaning they conduct, or allow electricity to flow nearly unimpeded. For example, the two most common forms of electrical wire are aluminum and copper. Here we will briefly discuss this resistance to electrical flow and why sizing wire correctly is so important.Įlectricity flows through and around a wire based on how much resistance the wire provides to the flow of electricity. The resistance in a correctly sized outbuilding electrical circuit (or any electrical circuit) will be a combination of material conductivity, distance, and load. When installing a circuit for your shed, the circuit will be dedicated to the outbuilding only, so that the power can be disconnected from the outbuilding without affecting the other circuits. Generally, electrical codes require individual circuits for bedrooms, bathrooms, laundry rooms, etc., so that the electricity can be disconnected one circuit at a time in case there is a problem. For example, homes usually have lots of circuits dedicated to individual rooms or zones, which can be disconnected by flipping the switch on a circuit breaker. A circuit is a closed loop of wire whose electrical power can be disconnected with a single switch. When you are planning to run power to an outbuilding that has never had power, you are in effect creating a circuit. What Should I Consider When Running a Wire to a Shed?
