Before removing an electrical panel deadfront, the inspector should FIRST:

UL 943 Class A GFCIs must trip at 6 mA or more and must not trip below 4 mA.

If the inspector finds a system shut down when they arrive (for example, the furnace breaker is off), standard SOP says they should:

Answer: Not operate it, and report that it was shut down

SOPs do not require inspectors to operate any system that is shut down, because restarting it may be unsafe.

On a correctly wired 120V receptacle, a multimeter reading from neutral to ground should be:

Answer: Near 0 volts

Neutral and ground are bonded at the service, so the voltage between them should be close to zero.

For a readily accessible and operable fireplace damper, the inspector should:

Answer: Open and close it

Inspection SOPs call for opening and closing the damper door when it is readily accessible and operable.

For windows in the interior inspection, the SOP requires the inspector to:

Inspectors operate a representative sample of windows rather than every unit.

When checking a freestanding range, what safety item should the inspector check for?
