If I were asked to check a piece of equipment already installed with no other information, this is what I'd check:
1. Check the voltage and amp requirements of the equipment
2. Verify it is fed from a panel and breaker of the proper voltage and amperage
3. Verify wireways are properly installed
4. Verify that proper size wire is used and that the equipment is properly grounded
5. Verify terminations are made properly
6. You may want to verify with a meter that proper voltage is being supplied. In most cases you can trust the labeling on the panel but it never hurts to check.
In all these verifications you are checking for workmanship, not just technically accurate installation. If something doesn't look right, check it out closely and look for other "red flags" that might signal someone didn't know what they were doing.
For single phase equipment and three phase equipment without a motor you are ready to turn it on. NEVER look at a breaker or equipment terminals when energizing. You only have one set of eyes.
For three phase motors you need to check rotation. This is done by "bumping" the motor by turning it on only for a moment. If it rotates correctly you are good to go. If it doesn't, switch any two leads either at the equipment or at the breaker and bump again. It should rotate in the right direction and should be ready to go.

Which IS a common sense safety procedure that can help prevent electrical accidents?
The main safety rule is to switch off at the mains before working on electrical equipment and wiring.
What must electrical equipment be tested for before it is used?
Any test equipment that your life may depend on when using it must first be tested before being used. These types of test equipment usually have internal apparatus that can verify that the equipment is working perfectly before it is used by personnel. Linesmen use this type of test equipment before working on primary voltage lines.

Why should you avoid bodily contact with ground while working on live electrical equipment?
No-one should work on live electrical equipment without training, and the training would answer that question. Always turn equipment off and unplug before doing any work.
What precautions should be taken to prevent electric shock sound while working with electrical equipment?
To prevent electric shock while working with electrical equipment, it is important to follow safety precautions such as wearing insulated gloves and shoes, using tools with insulated handles, ensuring equipment is properly grounded, and turning off power before working on electrical systems. Additionally, it is important to avoid working in wet conditions and to always follow proper safety procedures and guidelines.
What is the primary reason not to work on electrical equipment in a damp area?
Working on electrical equipment in a damp area can increase the risk of electric shock. Water is a good conductor of electricity and can lead to short circuits or malfunctions in the equipment, posing a serious safety hazard. It is important to ensure that the area is dry before handling electrical equipment to prevent accidents.
