Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Safety is the first thing assessors look for in any trade professional. This section covers the regulations, procedures, and practices that protect you and those around you on the job. Every answer here reflects a real-world scenario where the wrong choice has consequences.
Tanks: grey (sinks/showers), black (toilet); empty regularly, use RV-safe chemicals. 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.
Commissioning: test all appliances, check ventilation, verify safety devices work. 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.
Codes and standards define what's legal, what's safe, and what passes inspection. Every trade has its own regulatory framework, and the Red Seal exam tests whether you can navigate and apply those rules to real scenarios.
RV propane: CSA B149.1 adapted; second-stage regulator maintains steady pressure to appliances. Understanding and applying code requirements correctly ensures your installations pass inspection and meet legal obligations in your jurisdiction.
Calculation questions test your ability to apply trade math to real scenarios. Each formula has a purpose — know what it solves, what the variables represent, and how to check whether your answer makes sense.
Battery banks: size for 3-7 days autonomy; lithium = lighter, longer life, higher cost. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
lithium = lighter, longer life, higher cost
Understanding the tools, materials, and equipment of your trade — their properties, ratings, and proper applications — is what separates someone who works safely and efficiently from someone who causes problems.
Solar system: panels, MPPT controller (more efficient), batteries, inverter for DC/AC. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Shore power: 30A (12 AWG), 50A (6 AWG); GFCI protection on pedestal. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Slide-out systems: hydraulic most common; check seals, lubrication for proper operation. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Auto-leveling: jacks adjust independently to level RV; critical for comfort and appliance operation. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Leak sources: vent/AC seals (most common), window seals, roof penetrations. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Winterization: drain tanks, antifreeze in lines, disconnect batteries, weatherize seals. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
