For a 3-ton split-type air conditioning unit, a common recommendation is to use a 30-amp double-pole circuit breaker. This is based on the typical current draw of such units, which can range from 15 to 25 amps, depending on the specific model and its efficiency. It's important to consult the manufacturer's specifications for the unit to ensure the correct breaker size and to consider local electrical codes. Additionally, using the right gauge wiring is crucial for safety and performance.

For 8-gauge wire, the appropriate circuit breaker size typically ranges from 30 to 40 amps, depending on the specific application and the type of load being connected. It's essential to consider the wire's insulation type and the installation environment, as these factors can influence the breaker size. Always consult local electrical codes and a qualified electrician to ensure safety and compliance with regulations.
In North America this size breaker could be used on a welding machine. A range in the home would use a 40 amp two pole breaker.
3/4 hp of course consumes less electricty
For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.
A miniature breaker is just two breaker that fit into one breaker slot. These types of breakers are designed to install the same as a full size breaker. Different types of breakers have different mounting configurations to the panels bus bars so installation instructions are not possible without knowing the make and type.
The panel and breaker have to be of the same manufacturer. This way the breaker will fit into the panel. If the panel has a push in bus bar, the breaker must also be the type to accept the bus bar. If the bus bars in the panel are of the bolt in type then the breaker also has to be a bolt in breaker.
For a 60 amp breaker, a wire with a gauge size of at least 6 AWG should be used to ensure proper electrical safety and performance.
