• A. 50 amps
• B. 75 amps
• C. 100 amps
• D. 150 amps

Answer: (C)

The minimum service requirement for a new single-family home is 100 amps, which is considered a standard in most areas. This level of electrical service is adequate to handle the demands of typical household appliances and functions, such as lighting, heating, cooling, and kitchen equipment.

A service of 100 amps provides a balance that meets current energy needs while allowing for future expansions or additional electrical load, such as the addition of more appliances or electronic devices. This capacity ensures that residents can safely use their electrical systems without overloading the circuit, which can lead to tripped breakers or potential fire hazards.

While there are lower options, such as 50 amps or 75 amps, they do not accommodate the electrical demands of modern households and would likely result in an inadequate supply of power for today’s common electrical usage patterns. The 150 amps option, while beneficial for larger homes or those with specialized electrical needs, exceeds the minimum requirement, making 100 amps the standard baseline for new residential construction.
