![]() The total watts of the appliances must not be greater than 9600. You can check you are not exceeding this limit by checking the watts of each household appliance connected to the circuit and totaling the watts. The maximum wattage allowed on the circuit is 80% of this total, which for a 50-amp circuit comes out to about 9600 watts. The calculated wattage of a 50-amp circuit is 12000 watts at 240 volts. Most 50-amp circuits in a home utilize 240 volts instead of 120 volts for circuits that power smaller appliances. The total watts for all the devices and appliances connected to the 50-amp circuit must not exceed 80% of the calculated wattage. The electric water heater in your home is a prime example of this type of appliance.Ī 50 amp wire size circuits have a current limit and limit the number of watts the circuit can support. Many older homes use aluminum wiring, but most modern homes use copper core wires which are 61% more efficient for electricity transmission.Ĭertain appliances in the home require dedicated 50-amp circuits to which no other appliances are connected. You can use aluminum where cable weight and cost are factors since the aluminum cable is significantly lighter and cheaper than the copper equivalent. If your circuit wiring has an aluminum conductor, you need a wire of at least 4 gauge for compatibility with a 50-amp circuit breaker. This flexibility makes installing the thicker gauge wire through ducting or conduits much easier. Thick wires are not flexible, which poses problems when threading the cable through ducting.Ī stranded core is typically used in thicker gauge wires to add flexibility to the cable. ![]() The lower the AWG wire gauge number, the thicker the central core conductor. The central core of wires for 15, 20, and 30-amp circuits, 14, 12, and 10-gauge rating, respectively, is typically a solid core cable. The thickness of a 6-gauge wire size is 0.1620 inches or 4.115mm, but the wire gauge is generally clearly marked on the cable’s outer sheath. Household appliances in this category include electric stoves, ovens, washing machines, dishwashers, electric heaters, and hot tubs. The metal conductor is the only section that will carry the current.Ī 50 amp wire size in your home is intended for use with medium-heavy usage electric appliances. When a wire is measured to establish the gauge, only the thickness of the metal conductor is measured. Some circuits contain an aluminum core conductor wiring, which changes the wire gauge required for a 50-amp circuit.Įlectrical wires have three parts, the plastic sheath, the insulation around the metal conductor, and the conductor wire itself. The American Wire Gauge system standardizes the ratings for conductors with a copper conductor core. The 6 AWG copper wires are rated up to 55 amps, making it a good choice for this circuit. Feel free to change this number to suit your needs!Īfter inputting all the data listed above, you will see your result in the bottom-most field of the metal weight calculator.Wire Size for 50 Amp Circuit Breaker ExplainedĪccording to the American Wire Gauge system, the correct 50 amp wire size is 6 gauge. We have set 1 as the default option, so you can immediately see the weight of a single metal piece. Provide the material weight calculator with the number of metal elements. In some cases, we will also ask for the thickness of the metal element. For example, in the case of a rectangular metal sheet, the material weight calculator will need to know the length and the width of the rectangle to calculate its surface area, and, in the case of a circle, it'll ask you for the radius. In this case, we will ask you to provide the volume of the metal element.ĭepending on the shape, we will ask you to fill in some additional information that we need to calculate the volume of a single piece. Other - we have included the most common shapes in our metal weight calculator, but if you cannot find the one you're looking for, pick this option. In the latter's case, remember to switch the unit of thickness to millimeters or thousandths of an inch! ![]() Rectangular prism - note that this includes elements with a square as their base and very thin sheets of metal. The alloys have different densities, so picking the right one is crucial for the correct answer. Click the button to see a drop-down menu of various aluminum types (organized by their number). The average density of aluminum is the default option, but you have a long list of alloys to choose from. Start by picking the alloy you want to calculate the weight of. Please follow this short set of instructions on how to get your answer!
