Upon calculating your HVAC system size (tonnage), you will be shown a selection of systems that fit your recommended size. Note: For 10/2 (30 amp) use 1/2″ conduit and for 8/2 (45 amp) use 3/4″ conduit. A common residential heat pump condenser will have number 10 wire which terminates in the main electrical panel to a breaker specifically sized for the ampacity of the condenser. Both offer a measurement of an air conditioner’s cooling ability over an hour’s time. The term goes back to the production of ice. The breaker size is typically about 125% of the total of the compressor RLA and the condenser fan FLA (full load amperage). Get the cost of 1 ton, 2 ton, 4 ton and 5 ton ac unit. 1 Poor maintenance can cause air conditioner breaker trips. That will cause the air conditioner breaker trip if the problem is not repaired. Don`t want to argue but a 40 amp breaker is perfectly fine. With this increased power use, the heat increases. In the heat of the summer, one thing's sure to keep you cool and comfortable: a properly sized air conditioner. Breaker size depends on what is installed and length of wire. AC calculator uses your house size (square feet), climate zone, efficiency and equipment type (standard central air vs central heat pump) to show you exactly what size central air unit you need. Step 2: The air conditioner disconnect is connected to the air conditioner condenser with liquid-tight flexible metallic conduit, as shown in Figure 2.
