The maximum amp capacity of a circuit or electrical device is determined by the wire size and the rating of the breaker protecting the circuit. It is important to adhere to these specifications to prevent overheating and potential hazards. Consult a certified electrician for specific advice on determining maximum amp capacity for your application.
When you talk of the capacity of a service you are talking about the capacity of the equipment to handle a certain amperage. A 400 amp service has to have all of its equipment to be rated to handle 400 amps. The maximum capacity of the service will be what the service is protected at, be it with fused or breakers. If the fuses of the main breaker were 300 amp rated then the maximum capacity of the service would be 300 amp even though the equipment is rated at 400 amps. The service capacity is governed by the fusing that is protecting the service.
In a 200 amp load center, you should not exceed 80% of the panel's capacity to ensure safety and prevent overloading. Therefore, the maximum amp load you can install would be 160 amps. It's important to consult with a licensed electrician to determine the actual load requirements for the building.
Yes, a 1200 watt amp can power a 300 watt box. The wattage of the amp refers to its maximum power output, so it can deliver up to 1200 watts if needed. As long as the amp is set up properly and not pushed to its maximum capacity, it can safely power a 300 watt box.
15 and 20 amps for receptacles and lights, and anywhere from 20 to 60 amps for dedicated loads such as water heaters and air conditioning. The fuse size MUST be matched to the load and wire size, you cannot just arbitrarily pick one!
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.
