(Source: RCW 296-46B-920) Specialty is limited to the installation, repair, replacement, and maintenance of signaling and power limited circuits and related equipment. Specialty is restricted to low-voltage circuits and includes telecommunications, HVAC/refrigeration low-voltage wiring, fire protection signaling systems, intrusion alarms, energy management and control systems, industrial and automation control systems, lighting control systems, commercial and residential amplified sound, public address systems, and such similar low-energy circuits and equipment in all occupancies and locations. For the purposes of this section, when a line voltage connection is removed and reconnected to a replacement component located inside the control cabinet, the replacement must be like-in-kind or replaced using the equipment manufacturer's authorized replacement component. The line voltage circuit is limited to 120 volts 20 amps maximum and must have a means of disconnect. This specialty may repair or replace line voltage connections terminated inside the cabinet to power supplies internal to the low voltage equipment provided there are no modifications to the characteristics of the branch circuit/feeder load being supplied by the circuit. This specialty may not replace or modify the line voltage circuit or cabling or alter the means of connection of the line voltage circuit to the power supply or to the control cabinet. Contractors may perform all telecommunications work under this specialty license and administrator's certificate.
NOTE: Our study material for this exam will include sample questions for “Major Load Calculations” and “General Trade Knowledge” from Ugly's References, Chapter 9 Tables and Annex D of the NEC.
We highly recommend that you purchase one of the reference books above to study for your exam. Each book is a comprehensive subject index to the NEC. They provide an even faster way to look up answers in the code and are far more detailed than the index at the end of the code book.
NOTICE: For the calculations portion of the examination, Annex D in the NEC is a good source of examples. There are no questions from Annex D contained in our set of questions. Additionally, we give you a list of questions in our answer key that may apply to calculations. You will want to purchase a separate book that covers calculations in more depth like the one we recommend above.
Questions are sourced from the NEC and Washington statutes shown above.
Informaion is included about additional free sample questions and links to essential sources of electrical calculations to assist in drilling for your exam.
Additional bonus questions are included from Ugly's Electrical References.
The approx. number of practice questions in this package: 2,450
