Hi, I'm a Moderator for this topic. I've been working hard to find a Professional to assist you right away, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you. Thank you!

Thanks for using JustAnswer. My name isXXXXX will do whatever I can to answer your questions.

Don't Forget the deposit you placed to ask this question is not used to compensate me until you rate my service! Please Remember that when you are asked to give a rating, you are rating My Service and not this website itself.
I may be able to help on this but this is one that is not seen very often. They change the order of these tests regularly so it is not possible to really give an A, B, C answer key.

Can you post the questions here or upload the document using mediafire.com or wikisend.com and sharing the link here with me so I can take a look and see if I have the needed resources in my materials.

Also, what is the timeline to get returned to you?

Hi


 


here below is my question


 














1. A device box will house three No. 16/3 cables (each cable contains three insulated No. 16 conductors and one bare ground conductor), one switch, three cable clamps, and a grounding wire. No conductors run through the box without splices. Technician A wants to use a 4 × 21/8 inch round outlet box, while Technician B says that a 411/16 × 11/4 inch square outlet box should be used. Which technician is correct if your goal is to install the minimum size outlet box allowed by the NEC?
















A. Technician A
B. Technician B
C. Both Technician A and Technician B

A. 10 kΩ.
B. 100 kΩ.
C. 1,000 kΩ.
D. 10,000 kΩ.














8. If an appliance is said to be continuously operating, this means the electrician should

B. supply the appliance with a circuit sized so that 80 percent of the full-circuit capacity is greater than or equal to the appliance's current draw.
C. decrease the wire diameter to account for the additional resistance required.
D. always power the appliance with a pigtail-plug combination and never hardwire the appliance to a device box.














9. You're adding a new receptacle to an existing branch circuit and you find that the existing circuit contains aluminum conductors. The receptacle you're taking the power from is at the end of a run and is marked with the indication CU/AL. You want to route a copper cable from the existing device box to the new device box. You should replace the
















A. end-of-the-run receptacle with one that's approved specifically for through wiring with copper.
B. receptacle with one labeled FOR ALUMINUM ONLY, connect short lengths of aluminum wire to the ends of the copper cable, and install the exiting and new aluminum wires to the receptacle.
C. existing receptacle with any new conventional receptacle, then attach the copper and aluminum conductors to any of the receptacle's screw and pressure terminals.
D. existing receptacle with one labeled CU/ALR, attach the aluminum conductors to the receptacle's screw terminals and insert the copper conductors into the pressure terminals.














10. Technician A says that troubleshooting parallel circuits is done by isolating a circuit component before measuring its resistance.
