2 Ton Ac Wire Size

A 30 amp circuit requires a minimum of 10 wire.

2 ton ac wire size.

These line sizing charts are based on a suction pressure drop equivalent to a 2 f change in saturation pressure and liquid line pressure drop of 5 psi. If it s more than 50 run 8 2 or 8 3. On average homeowners report spending 3 900 5 000 to install a 2 5 ton central air system in a house that has functional ductwork. The disconnect must be within reach of the condensor if the condensor is single phase then you only need to run 6 2 stranded with ground.

Before we get into sizing a residential central air unit lets take a quick look at pricing. This is a general guideline for home wiring. All loads are categorized into two types. For r 404a and r 22 medium temperature 2 psi is used.

Table 310 16 shows that three wires of 6 gauge placed in a conduit will safely conduct 65 amperes of power. A disconnect is required per code. Air conditioner or heatpumps need to have wiring sized for 125 of ampacity requirements after derating for bundling or ambient temperature. Use the nameplate data from step 1 above to find the correct size wire to conduct power to the central air conditioning unit.

12 is for a 20 amp or less circuit. This is the maximum allowable pressure drop for the entire piping run regardless if it is 50 or 250. Don t forget that devices with motors designed for continuous running e g. Depending on the size of the equipment and what the length of the run is will determine the wire size.

Look at the amperage rating on the unit. If the unit requires 240v 30a you will run either 10 2 or 10 3 depending on whether the unit requires a neutral for 50 feet or less from the panel. This is a 2 ton air conditioner as you can see from the model number. For r 404a low temperature 1 psi.

The whole content is written for single phase 230v ac system. The voltage range for this wire falls between 0 volts and 2 000 volts. Most residental units are single phase. There are already many good answers but i will still mention some important points.

Here s a picture of an air conditioner s data tag that i took just today. The data plate on the condenser reads 1ph 208 230 nominal volts min ckt ampacity 17 2 max fuse or circuit breaker 30 amps hacr my run is 50 to 60 feet from breaker panel to disconnect. At least here in florida. Central ac unit cost.

Fixing or changing the ductwork to accommodate the ac system can add as much as 3 000 4 000 to the total price. You can see that right well trust me.
