Is a load(appliance) that runs at max current for 3 hours or more at a time.
For a continuous load the circuit breaker is set 25% higher than the load current. So a 20-amp breaker is used with a continuous 16-amp load.
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.
I'd try to stay about 16 amps to prevent the breaker from nuisance tripping. That is as many as 32 - 60 watt incandescent (normal) lights or 83 - 23 watt CFLs. In practical terms it is hard to overload a single circuit with lights or other small loads (just about anything using a receptacle except the obvious AC unit or vacuum cleaner).
As stated in the electrical code, circuits are to be loaded to 80 percent of the total capacity when operating in a continuous state..
200. Although you cannot exceed current ratings on any branch circuit without tripping that circuit. You need to make sure that you do not exceed 160 continuous load amps to meet NEC requirements of not overloading a breaker to more than 80% under continuous load.

The maximum current rating for the circuit breaker should be at least 30 amps to accommodate the continuous current of 25 amps required by the load.
80% of 40 = 32 amps Load the circuit breaker to 80% choose a conductor to suit the circuit Breaker min.

This depends on your local electrical code, however the National Electrical Code and Canadian Electrical Code both state that you must derate circuits to 80% of their maximum electrical capacity, so for a load of 75 amps you must use overcurrent protection and wire rated for 93.5 amps, and since that doesn't exist you must upsize to 100 amps.
Yes, you can have an 18 amp appliance on a 20 amp circuit. It is important to leave some room for safety margin, and a 20 amp circuit should be able to handle the 18 amp load without any issues. Make sure the wiring and circuit breaker are correctly rated for the load.
A 30 amp breaker is designed to handle a maximum continuous load of 30 amps, while a 40 amp breaker can handle a maximum continuous load of 40 amps. The 40 amp breaker allows for more current to flow through before tripping, making it suitable for higher power requirements compared to the 30 amp breaker. Always consult with a qualified electrician before adjusting or replacing circuit breakers to ensure safety and compliance with electrical codes.
The maximum continuous load for a 20 amp breaker is 16 amps. This accounts for the 80% rule, which states that you should not exceed 80% of the circuit breaker's capacity to prevent overheating and potential fire hazards.
If the load is continuous you need to observe 80% rule. A 20 Amp breaker will handle short term loads that exceed 16 Amps. Think about it as a heat issue where continuous higher current will heat up components to unacceptable levels.
