1) As per the NEC, the distance measured horizontally from an underground tanks fuel vent is how many feet to be in a classified area/zone?
A) 18 B) 20 C) 25 D) 30
2) Under article 680 (Swimming pools), Give the maximum diameter for decorative fountains before they are subject to NEC requirements.
A) 2’ B) 4’ C) 6’ D) 8’
3) A motor control start button is normally open, momentary. Note: mechanical, not PLC
True False
3) What size conductor from the 75c column would you use for a mobile home parks main service, knowing the net computed volt-amperes is 387,000 VA. The service is 120/240V single phase.
A) 4 sets 600kcmil B) 3 sets 500kcmil C) 4 sets 400kcmil D) 1 set 750kcmil
4) Voltage drop is considered by the NEC as “practical” at what percentage of supply service entrance to the last over current protective device?
A) 5 B) 4 C) 3 D) 2
5) How many four way switches are needed to control a lighting fixture from 5 locations?
A) 3 B) 4 C) 5 D) 1
6) What is the identification color for a service 120/240 single phase grounded conductor?
A) Any, so long as marked at main B) White or natural grey C) Green or bare D) Orange
7) What is the ampacity of a #10AWG copper THHN as per 310.15(B)(16) column 90c ?

8) In dwellings, a main panel with breakers or fuses can be installed in room with a toilet?
True False

A) 4 B) 7 C) 8 D) 10
10) Given: 3- 40 ohm resistors, 2 – 100 ohm resistors connected in series will draw a current of:_______
At a voltage of 120V.
A) 0.375 B) .0380 C) 3.075 C) .320
These are "starter" questions 1-10 for master electrician license in PA (yes we are trying our best to get it but who has that kind of money to lobby?)
Anyway - Answer them and toss your positive or negative feedback to me. I wanna know they are fair questions to ask. Ps assume all copper
