Question

If you measure 20 feet between an existing box and a new box location, you should cut a piece of cable with a length of approximately

A. 20 to 21 ft.
B. 25 to 26 ft.
C. 40 to 42 ft.
D. 48 to 55 ft.

Answer 1

For a measured distance of 20 feet between two boxes, the correct length of cable to cut should consider additional slack for installation. The best choice would be 25 to 26 feet, accommodating for bends, connections, and securing the cable. So the correct option is B

Step-by-step explanation:

When you measure 20 feet between an existing box and a new box location and you need to cut a piece of cable, you should consider not only the distance but also any additional length that may be required for securing the cable or for any unforeseen issues like obstacles or corners. Therefore, while the straight-line measurement is 20 feet, it's prudent to add a bit of extra length to ensure that the cable can be properly installed without being too short. The option that provides a reasonable additional length, considering the need for slack, connections, and bends, would be:

• B. 25 to 26 ft.

Therefore, the correct answer would be B. 25 to 26 ft, as it allows for both the measured distance and reasonable extra length for installation.

Answer 2

A. 20 to 21 ft.

Step-by-step explanation:

You measured 20 feet from point A to point B, simple so its around 20 feet and some extra inches possibly to account for miscalculations somehow.

Now unless we're surrounding a box or doing more you really shouldnt need anything more.
