CEI Plan Review & Permit Processing 3

Question 1

Under NEC Article 220, which method is commonly used to calculate residential service loads for plan review purposes?

Accepted Answer

Optional calculation method (220.82)

Answer

NEC 220.82 provides the optional calculation method most commonly used for existing and new single-family dwelling service sizing.

Question 2

During review of a tenant improvement permit, the plans show new receptacle circuits but no panel schedule update. What should the reviewer require?

Accepted Answer

An updated panel schedule showing new circuits and remaining capacity

Answer

An updated panel schedule must be submitted to verify available capacity and document circuit assignments for inspection purposes.

Question 3

What is the maximum time the AHJ typically has to act on a permit application before it is considered approved by default, according to most model codes?

Accepted Answer

There is no default approval provision in model codes

Answer

Most model codes, including the IBC and IEBC, do not provide for automatic approval by default; the AHJ must take action on the application.

Question 4

A contractor submits plans stamped by a licensed engineer showing a 3-phase 208V panel fed from a 480/277V system without a transformer on the drawings. What should the reviewer do?

Accepted Answer

Request clarification or correction to show the step-down transformer

Answer

The reviewer must ensure the drawings are complete and internally consistent; a missing transformer feeding a 208V panel from a 480V source is a critical omission.

Question 5

Which of the following is NOT typically required on electrical permit drawings for a new commercial building?

Accepted Answer

Equipment manufacturer's installation manuals

Answer

Manufacturer installation manuals are not typically submitted with permit drawings; the plans must reference listed equipment, but manuals are field documents.
