a) In suspension insulator numbers of insulators are connected in series to fom a string and the line conductor is carried by the bottom most insulator. Each insulator of a suspension string is called disc insulator because of their disc like shape. Briefly describe the advantages and disadvantages of suspension insulator used in transmission lines. b) These are mainly THREE (3) main methods generally used for protection against lightning. With aid of illustration, using your own words, explain the concept and drawbacks of cach methods used for substation against lightning. c) Using your own words, briefly describe the concept, drawbacks, and ways to overcome the transient overvoltage in power system network.

Most residential general lighting circuits are wired with 14-AWG copper conductors and are protected by 15-amp circuit breakers. However, there are many electricians who install 12-AWG copper conductors and protect them with 20-amp circuit breakers. How will you know which conductor size and which circuit breaker size will be used for the general lighting branch circuits in the house you are wiring?

Electrical Engineering What is the smallest square box that will accommodate four No. 12 conductors and four No. 10 conductors if a. These conductors are pulled through without a splice? b. These conductors are all spliced in the box?
From time to time, depending on the conductor size, an electrician has to re-identify a conductor as a grounded conductor or a grounding conductor. Wrapping the conductor with green electrical tape is the most common way to re-identify a grounding conductor. White tape is used to re-identify a grounded conductor. Discuss the difference in the way a grounding conductor is re-identified with green tape and how a grounded conductor is re-identified with white tape

The Aluminum Electrical Conductor Handbook lists a dc resistance of 0.01558 ohm per 1000 ft at 20C and a 60-Hz resistance of 0.0956 ohm per mile at 50C for the all-aluminum Marigold conductor, which has 61 strands and whose size is 1113 kcmil. Assuming an increase in resistance of 2 for spiraling, calculate and verify the dc resistance. Then calculate the dc resistance at 50C, and determine the percentage increase due to skin effect.
