Final answer:
For fixed in place X-ray equipment, the branch circuit should not exceed c. 50 Amps when supplied through a suitable attachment plug cap and hard service cable cord, ensuring safe operation within standard electrical practices.
Step-by-step explanation:
Fixed in place X-ray equipment, which has significant power requirements, is one application that necessitates particular considerations when it comes to electrical supply. For safe operation and to adhere to electrical codes, the branch circuits supplying this equipment must be correctly rated.
Typically, circuit breakers in a home vary from 10 to 30 amperes, based on the demand of various appliances. For example, a living room might have several outlets protected by a single 15-amp circuit breaker, while a refrigerator might be on a separate 20-amp circuit breaker. These breakers prevent damage to appliances and protect residents from electrical hazards.
Another important aspect to understand is the continuous use limitation, which limits the use to 80% of the circuit breaker's rated capacity. This is why you don't usually see residential heating appliances rated over 1500W.
In the case of X-ray equipment, if it is to be supplied through an attachment plug and hard service cord, there is a limitation on the amperage of the branch circuit that can be used. According to standard safety practices and regulations, the branch circuit for such equipment should not exceed a certain amperage. Considering the options provided, the most appropriate answer would be 'c. 50 Amps', ensuring that the equipment is operated within a safe limit and preventing potential electrical hazards.
Therefore, when the question states, 'Fixed in place X-ray equipment properly supplied by a branch circuit rated at not over ____ amperes shall be permitted to be supplied through a suitable attachment plug cap and hard service cable cord,' the correct option in the final answer is 'c. 50 Amps'.
