Texas Master Sign Electrician Exam
Batch 1 (Questions 1–50)
1. A Texas Master Sign Electrician is reviewing plans for a new illuminated pylon sign installation.
According to TDLR regulations and licensing requirements, which responsibility belongs directly to the
Master Sign Electrician supervising the work?
A. Ensuring electrical work complies with applicable NEC and state requirements
B. Delegating all code compliance responsibility to the sign owner
, Page 3 of 129
C. Ignoring permit requirements if the sign is privately owned
D. Performing only non-electrical portions of the installation
Answer: A
Rationale: The Master Sign Electrician is responsible for ensuring electrical installations comply with
Texas regulations, TDLR requirements, and the NEC.
2. An electrician measures 120 volts across a sign circuit and 10 amperes of current flowing through the
load. Using electrical power calculations, what is the power consumption of the circuit?
A. 1,200 watts
B. 12 watts
C. 120 watts
D. 12,000 watts
Answer: A
Rationale: Power equals voltage multiplied by current. P = V × I = 120 × 10 = 1,200 watts.

3. A sign technician is troubleshooting a circuit containing 240 volts and a measured resistance of 24
ohms. According to Ohm's Law, what current should be flowing through the circuit?
A. 10 amperes
B. 24 amperes
C. 5 amperes
D. 48 amperes
Answer: A
Rationale: Current equals voltage divided by resistance. I = V ÷ R = 240 ÷ 24 = 10 amperes.
4. During a code-compliance review, an installer must locate requirements for electric signs and outline
lighting systems. Which NEC article should be consulted first?
A. Article 600
B. Article 430
