![]() ![]() If electrical wires get too hot, the insulation can melt on the inside, leading to a fire happening.įor example, suppose you have a relatively large heat pump with 24,000 BTU, yet your wire is only a 12 gauge. The wire size is essential because an overload can occur if it is not sized appropriately. Residential systems are often limited to a maximum of 5 tons or 60,000 BTU. AC Size BTU American Wire Gauge (AWG) Size Breaker Size 1 ton 12,000 14 gauge 15 amp 1.5 ton 18,000 12 gauge 20 amp 2 ton 24,000 10 gauge 25-30 amp 3 ton 36,000 8 gauge 30-40 amp 4 ton 48,000 6 gauge 50-60 amp 5 ton 60,000 4 gauge 60-70 amp 6 ton 72,000 2 gauge 80-90 amp 7 ton 84,000 1 gauge 100-125 amp Breaker sizes and wire gauges vary depending on the manufacturer and model. The outdoor unit should specify the MCA (Minimum Circuit Ampacity) and MOCP (Maximum Overcurrent Protection) on its plate. The minimum ampacity helps determine the minimum gauge wire you need to use.įurthermore, we have provided tonnage table charts below if you are a visual person and need a better reference. ![]() Wire gauges are measured in diameter based on the American Wire Gauge (AWG) chart. If you have your average 240 volts 2 kW air handler, you will need a 30 amp breaker and a #10 electrical wire. Let us say you have a 2-ton heat pump at home. That information also provides you with the maximum overcurrent protection or MOP rating. In return, it makes it much easier to determine what size breaker you need. If you are still unsure how to follow this guide, you can quickly look at the nameplate data on the outdoor unit. Not only that, but the amount of voltage the heat pump needs also determines the size of the breaker. What Wire Size and Breaker for Heat Pump? (Tonnage Chart)ĭepending on the size wire, you’ll need to find the breaker’s size, which gives you the specific rating. Given that information, the main power panel has two separate breakers for the air handler and the other one for the heat pump condenser. A regular heat pump requires two dedicated branch circuits: the condensing or AC unit and the air handler. It is essential to know how many breakers you will need for a split heat pump or central AC in the first place. Keep reading to find out more information and what wire and breaker sizes are needed for your central cooling system. Manufacturers list the maximum breaker size on the data plate located on the side of both units. There are 8 increments of sensitivity that the unit can be programmed to.The wire size and breaker for heat pumps and air conditioners (AC) vary based on the tonnage. However, one might wonder how many amp breakers you need for a heat pump.Ī split heat pump or air conditioner has two separate electrical circuits, one for the outdoor unit (condenser) and the indoor unit (air handler or furnace). The main electric panel contains two different amp breakers one for the indoor unit and the other for the heat pump condenser or air conditioner. If the vehicle’s windows are open we do not have a measurement for how far away the unit will work. The RFID is capable of working between 5 and 200 feet with the vehicle’s windows closed. Should your fob become lost or damaged you can over-ride the system by entering a code with the hidden button switch. The RFID fob must be in range for car to start and will stay running until the operator turns it off, then it won’t restart. The car only starts and stays running with the RFID fob in range. The RFID unit has 3 different operating modes. And, just as a magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information. ![]() The RFID device serves the same purpose as magnetic strip on the back of a credit card it provides a unique identifier for that object. The acronym refers to small electronic devices that consist of a small chip and an antenna. RFID stands for Radio-Frequency Identification. This all new RFID Security system gives you the security and convenience that today’s society demands. This is the security system that your hot rod has been missing.Īs you may already know the “HOT DOT” ignition takes the place of your conventional “keyed” ignition switch however it has no security built in. ![]() This all new StreetWorks RFID is designed to work with your Hot Dot Ignition Systems or your existing key. ![]()
