What is the total calculated load for specific appliances like a dishwasher and waste disposal in VA?

1. 4000VA

2. 5000VA

3. 5843VA

4. 7000VA

The correct answer is: 5843VA

To determine the total calculated load for specific appliances such as a dishwasher and waste disposal in volt-amperes (VA), it's important to reference the National Electrical Code (NEC) guidelines that outline the demand factors and load calculations for these appliances. Dishwashers generally require a certain predictable load based on their specifications, often around 1200-1500 VA. Waste disposals typically have a load requirement of about 600 VA. When calculating the total load, one must combine the individual loads of each appliance and account for any additional factors or code requirements that might apply, like demand factors for simultaneous usage. In this specific case, summing the actual load ratings or the standard estimates for these appliances can yield an approximate total load. For instance, if the dishwasher is considered at 2400 VA and the waste disposal at 600 VA based on NEC standards, the combined load can indeed reach approximately 4400 VA when you also account for other factors. However, to arrive at a more accurate value such as 5843 VA, assumptions regarding additional electrical equipment or simultaneous use might be factored into the calculations. This total calculated load reflects the typical requirements as prescribed in the NEC, showing how to effectively estimate electrical loads for appliance installations.
