CET content outline and where to practise each area

The content areas below are copied from the official CET content outline published by National Association of Elevator Contractors. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through CET questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: How must traveling cables be attached at the car and at the overhead support point?

1. With cable ties spaced every 12 inches along the cable run
2. With strain relief so that conductors are not subjected to tensile stress at terminations
3. Welded directly to the car sling frame for a permanent connection
4. With spring-loaded connectors that allow free movement in all directions

Answer: B. With strain relief so that conductors are not subjected to tensile stress at terminations

Explanation:

Strain relief is correct. A traveling cable hangs from the car and carries the weight of its own length, and it flexes on every trip. If the conductors carry that pull, the copper fatigues and breaks at the terminals. Strain relief puts the load on a support so the conductors are free of tensile stress.

Cable ties spaced every 12 inches are wrong because ties are not a rated way to carry the load and can pinch the jacket. Welding the cable to the car sling frame is wrong because a rigid, heated joint creates stress and prevents the cable from flexing as designed. Spring-loaded connectors that allow free movement in all directions are wrong because uncontrolled movement causes chafing and fatigue.

Rule to remember: mechanical load goes to a support, never to an electrical termination.

Example 2

Question: Which condition would most likely cause loss of traction in a traction elevator?

1. Sheave groove wear causing increased rope contact
2. Overloaded car creating too large a traction ratio between loaded and unloaded rope sides
3. Excessive rope tension on both sides equally
4. Proper lubrication of drive sheave grooves

Answer: B. Overloaded car creating too large a traction ratio between loaded and unloaded rope sides

Explanation:

An overloaded car is correct. Traction depends on friction between the ropes and the sheave grooves. That friction can resist only a limited difference between the tension on the car side and the tension on the counterweight side. A heavily loaded car widens that difference, and when it passes the limit the ropes slip.

Sheave groove wear causing increased rope contact is wrong because more contact generally helps grip, and the real wear problem is grooves that change shape in ways that reduce it. Excessive rope tension on both sides equally is wrong because equal tension does not create the imbalance that causes slipping. Proper lubrication of drive sheave grooves is wrong because it describes normal practice, not a fault condition.

Rule to remember: slippage comes from a large tension ratio across the sheave, not from the absolute load on either side.

Example 3

Question: What is 'rope creep' in a traction elevator system?

1. Gradual rope elongation under constant load
2. Slow slippage of hoist ropes relative to the drive sheave under traction
3. Movement of ropes through the sheave grooves due to overloading
4. Lateral movement of ropes across the sheave face

Answer: B. Slow slippage of hoist ropes relative to the drive sheave under traction

Explanation:

Slow slippage of hoist ropes relative to the drive sheave is correct. Rope creep happens because the ropes on the loaded side are stretched slightly more than those on the other side, so they move a little relative to the sheave as they pass over it. It is small, gradual and part of how traction drives behave.

Gradual rope elongation under constant load is wrong because that describes stretch, which changes rope length, not its position on the sheave. Movement of ropes through the grooves due to overloading is wrong because that describes a loss of traction, which is a fault and a much larger event than creep. Lateral movement of ropes across the sheave face is wrong because creep follows the direction of rope travel, not sideways drift.

Rule to remember: creep is small relative motion along the groove; lost traction is gross slipping.

How to use these practice tests

Start with the official material, because the exam is open book and the handbook is the source that counts. Read the CET handbook on the NAEC site and list the content areas shown in the table above. Mark the ones where you work every day and the ones where you rarely touch the equipment, such as escalators, dumbwaiters or hydraulic units if you mostly service traction cars.

Next, take the practice set for your weakest area and read every explanation, including those for questions you got right. When you miss a question, do not just note the answer. Find the matching section in your handbook or code book and write down where it is, because on test day that skill of locating the right page quickly is what an open book exam rewards.

Then rotate through the other sets, returning to the weak ones after a break so you are recalling, not rereading. Use the worked answers on this page as a model for how to reason: say why the right option works and why each wrong option fails. Finish with a full pass through the general practice test to check that your topics hold together, and keep your reference material tabbed and ready.
