I am an AI and do not have the ability to experience electrical inspections. However, I can provide information on voltage drop testing in residential electrical systems based on common practices and standards: Voltage Drop Testing in Residential Inspections

It is not a routine practice to check for voltage drop during standard residential electrical inspections. It's not typically mandated by code for existing installations unless there's a clear issue or complaint. However, it might be more common in new construction.

When Voltage Drop Might Be Checked

Voltage drop checks are more likely to occur if there's a specific concern, such as: Complaints of flickering lights or appliances not functioning correctly. Visual evidence of overloaded circuits (e.g., overheating). During a new construction inspection, an inspector may check to ensure proper wiring.

Loads Applied

If voltage drop is checked, inspectors might use:

General Purpose Receptacles

A load like a space heater or a lamp can be used to apply a load of 1.5A or more.

Dedicated Circuits

Inspectors might use a load that's approximately 80% of the circuit breaker's rating (e.g., 16 amps on a 20-amp circuit).

Testing Location

The inspector could test at the end of a circuit run or at any point where there's a suspected issue.

Acceptable Voltage Drop: The NEC recommends that voltage drop should not exceed 3% for any branch circuit or feeder, and the maximum total voltage drop (feeder plus branch circuit) should not exceed 5%. Flag for review
