What type of fuse is typical for an air conditioner?
Answer: If your A/C is rated for 35 amps, then you can use a fuse 35 amps or smaller, but not too small. There should a minimum fuse size rating as well for the unit. The disconnect needs to be rated properly as well, however, or your fuse size becomes a moot point.
How many amps do you need for central air?
Central AC Electrical Requirements Central air conditioning units require 208/240 volts. They must be hard wired and have a dedicated circuit. Units require anywhere from 15-60 amps depending on how many tons they are.
What kind of Breaker do I need for central air?
It’s going to completely depend on the unit that’s being installed, but commonly it’ll be 30-60 amp with 10-4 AWG wire. You’re probably looking at a 3.5 ton unit, so you’ll be in the 30-40A (10-8 AWG) range. It might be worth it to get a few quotes from local HVAC companies, and see what they want to install.
Do you need 200 amp service for central air?
As a general rule, anything less than 100 amps will require an upgrade to support a modern HVAC system. Most residences will need at least 200-amp service to provide adequate power for the condenser unit along with other major home appliances.
Is 100 amp service enough for a house?
Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.

Can you plug an air conditioner into a regular outlet?
If the AC does not have a standard grounded plug, it must require more than 13 amps. If it requires no more than 15 amps, it could be connected to the proposed circuit, but code requires that there be no other outlets on the circuit. If it requires more than 15 amps, it requires a higher capacity circuit.
