- How is the required number of branch circuits determined? __________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?What kind of cable uses BNC connectors?
- What is grading of cables.Explain?a. Does the circuit for the Master Bedroom have a grounded circuit conductor? ____________________ b. Does it have an equipment grounding conductor? ____________________ c. Explain the difference between a grounded conductor and an equipment grounding conductor. ____________________ ____________________How are the male and female terminals removed and replaced in a multipin connector?
- The wording that I am running into with questions such as "The number of conductors required to be installed between three-way and four-way switches is " is confusing. The text is not expalining this in a way that I am understanding anything other than grounding conductor, which is optional unless I am using a metal box. So what type of "conductor" is beng discussed?12 - Due to the effect of the resistance of the cable connected to RTD, two-wire cables up to ……. meters and three-wire cables up to ……... meters are used in standard designs. A) 10-150B) 40-500C) 50-195D) 30-230E) 200-10002. What fault occurs when Line and Neutral wires come with each other? Which device is actuated?
