Question 10

10

Interior metal gas piping in a residence must be bonded. To which of the following is it permitted to be bonded per NEC 250.104(B)?

Question 11

11

A dwelling unit has a gross floor area of 1,800 sq ft. Using the NEC standard method, what is the general lighting load in VA before any demand factors are applied?

Question 12

12

In a standard residential load calculation, what demand factor is applied to a single electric clothes dryer in a single dwelling unit?

Question 13

13

When applying the NEC optional calculation method for a single-family dwelling service, all load above the first 10 kVA is multiplied by what percentage?

Question 14

14

A 20A, 120V branch circuit supplies a single receptacle. What is the maximum continuous load that may be placed on this circuit per NEC requirements?
