For example: Keep this in mind, especially when typing numbers into your calculator. 9 Table 8, and the wire ampacity is from Table 310.15(B)(16). 8.6kw ÷ 240V = 35.8A. The goal is to be able to understand the technical lessons of the main course, not become frustrated or fall behind the other students. Refer to Section 210.62. Multiplying or dividing a percentage is easier when you first convert the value into a decimal and use the new number in your calculation. It’s similar to static electricity, and is entirely normal. in. Electrician Math: Life-Saving Skills. Electric engineering Problems, exercises, etc. For help with math calculations on electrician license exams, the following two books written by Ray Holder (Master Electrician and Certified Electrical Trade Instructor) focus on math and show you, in a step-by-step way, how to solve electrician math problems: To solve this problem apply the single-phase current formula: I = P ÷ E. Incorrect answer. Each component (resistors, capacitors, inductors, etc.) Return to the Electrician Information Resource homepage to explore more topics. Quiz yourself with over 100 electrical engineering worksheets. Before you begin to track down the cause of any electrical issue, it’s a good idea to refer to equipment or operation manuals and drawings. 40A. To solve this problem, first find the temperature adder, 40ºF, from Table 310.15(B)(3)(c) due to the proximity of the conduit to the rooftop exposure to sunlight then, add this value to the outdoor ambient temperature: 352.44 states that an expansion coupling is needed if the conduit will change more than 1/4" in length in a straight run. Identify problems from the list below, as well as the most appropriate solution. 314.16(B)(4) requires a double volume allowance based on the size of wire connected to the device - #12 wire being 2.25 cu. PDF. Before we go there, we understand that when it comes to minor issues that pose no threats, you will probably prefer to do it on your own.
