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?

Four No. 12 and four No. 10 conductors are to be installed in a EMT conduit 600 V jacketed. What size EMT conduit is required if a. The conductors are Type T90 Nylon? b. The conductors are Type RW90?

h.1. In an alternating-current system, the maximum size for a copper grounding electrode conductor isA. 250 kcmil.B. 3/0.C. 500 kcmil.D. 4/0. h.2. The figure shows a fault condition in an ungrounded electrical system. Which of the following will occurbecause of the fault in this system?A. Only the overcurrent protector at Point A will trip open.B. The ground fault will heavily damage the service.C. Nothing will happen until a second ground fault occurs.D. The overcurrent protection will trip, shutting off all the line side power.

Need help with second question if all that would be helpgul

i need the answer quickly

12. A short circuit describes the condition where there's contact between theA. hot wire and the neutral wire.B. grounded conductor and the grounding wire.C. hot wire and the grounding wire.D. neutral wire and the grounded conductor. I'm not sure if it's the letter A or C, could you help me with the correct answer.

15. What does a grounding symbol on a construction drawing convey?A. A single ground rodB. A grounding electrode systemC. A ground-fault current pathD. An equipment grounding conductor

How the required number of branch circuits can be determined?

Multiple Choice. Refers to a point in a circuit where three or more wires are connected. A. Conductor B. Junction C. Loop D. Resistor

4. Disconnect the DC power supply, and then measured the equivalent resistance by using the AVO meter only.
