If you decide to go this route, it does not change the circuit’s number of tamper-resistant outlets. However, it is possible to wire a light into a 20-amp circuit and be within code. The general standard is to wire lights on 15-amp circuits and outlets on 20-amp circuits. The NEC allows for connecting light-fittings to a 20-amp circuit, but it is best to put lights on their own, independent circuit from a practical point of view. It is preferable to keep lights and outlets on separate circuits. How Many Outlets and Lights Can You Put On a 20-Amp Breaker? This split will give you capacity on both circuits for future expansion, should you need it.
#20 amp breaker install
For example, if you need 12 outlets, the best solution would be to install two 20-amp circuits and put six outlets on one circuit and six on the other. The best option in this circumstance would be to split the number of circuits over two 20-amp circuits.
The extender may seem like a solution to limited outlets, but it can be dangerous, particularly if the extender plug itself does not have any overload protection. The first thing most people do is purchase an extender plug that allows them to connect multiple devices to a single outlet. When there are insufficient electrical outlets in a room in your house, the possibility of overloading a circuit becomes a genuine problem. What If You Want More Than 10 Outlets On a 20-Amp Circuit? We round down the calculation result down to achieve our ten outlet maximum on a 20-amp circuit. Here is the calculation for our 20-amp circuit. This measure is one outlet for every 1.5 amps up to the 80% maximum usage. The reasoning is that a constant current draw close to the circuit’s maximum capacity will cause the conductors in the wiring to generate heat, which can potentially pose a safety risk.Ī rule-of-thumb measure establishes how many outlets you can connect to the circuit without exceeding the 80% usage limit. The NEC provides leeway for appliances drawing a spike current that will exceed this 80% limit for a short time but not for extended periods. The calculation to work this number out is as follows. On a 20-amp circuit, the 80% continuous capacity rule restricts the maximum constant current to 16 amps.
#20 amp breaker code
The NEC or National Electric Code stipulates that a circuit can draw continuous current up to 80% of its rated load. How do you know the number of receptacles or outlets you can connect to the circuit? The answer is quite simple and can be derived using a basic calculation. Circuit Wire Gauge 15-amp 14-gauge 20-amp 12-gauge 30-amp 10-gauge 40-amp 8-gauge 50-amp 6-gauge 60-amp 4-gauge Here is a quick wire-gauge chart for standard circuit sizes for your convenience. Connecting a 20-amp circuit breaker to the 12-gauge wire creates a circuit rated as a 20-amp circuit. What Size Wire Is Needed For 200Amp Electrical Service – Home Inspection InsiderĪccording to the American Wire Gauge or AWG standard, the minimum wire gauge size for a 20-amp circuit is 12-gauge.
