Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Safety isn't optional in the electrical trade — it's what separates professionals from statistics. The exam will test your knowledge of arc flash protection, LOTO procedures, PPE selection, and WHMIS requirements. Master these, and you're protecting yourself, your crew, and your license.
HART: superimposes 1.2 kHz FSK signal on 4-20mA allowing simultaneous analog + digital. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Electrical calculations are the backbone of proper installation — undersized wire causes fires; oversized breakers don't protect equipment. Every formula on this exam has a practical application: sizing conductors, calculating demand loads, determining motor current, or checking voltage drop. Know the formula, understand the variables, and practice the math.
Pitot: static (side) vs. total (front) ports; velocity = √(2ΔP/ρ). Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
velocity = √(2ΔP/ρ)
Orifice: hole diameter relative to pipe diameter; pressure drop = flow function. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
pressure drop = flow function
RTD: Pt100 (100Ω @ 0°C, ±0.15°C), reliable, linear; industrial standard. Understanding and applying code requirements correctly ensures your installations pass inspection and meet legal obligations in your jurisdiction.
PID: P = speed, I = steady-state error, D = damping; tune for stable response. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
P = speed, I = steady-state error, D = damping
Every conductor, conduit, fitting, device, and panel component has specific properties that determine where and how it can be used. Knowing the right material for the application — conductor type, conduit fill, box sizing — is exactly what the exam tests here.
Thermocouples: J (iron/copper-nickel), K (nickel/aluminum-silicon), T (copper/copper-nickel). Safety regulations exist because the consequences of ignoring them are severe — injury, death, or legal liability. Know these requirements the way you know your own name.
Calibration: pressure pump, digital manometer; record 0%, 50%, 100% for linearity. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
ISA tags: PT = pressure transmitter, FT = flow, TT = temp, FCV = flow control valve. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
PT = pressure transmitter, FT = flow, TT = temp, FCV = flow
Valves: globe (precise), ball (quick), butterfly (low dP), diaphragm (small). Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Installation technique affects reliability, safety, and code compliance. How you support a cable, how you make a splice, how you size a box — these details matter on the exam and on the job. This section covers installation methods, testing procedures, and the troubleshooting logic that experienced electricians use.
4-20mA: current loop, 4mA offset allows <4mA = broken wire detection. Understanding and applying code requirements correctly ensures your installations pass inspection and meet legal obligations in your jurisdiction.
mA = broken wire detection
