Installation
Instructions
:
Install NMSC from the breaker panel to the required outlet boxes.
Be sure to install according to the CEC rules. (i.e., points of support, correct length of wire in box).
Connect switch to control a lamp,
Connect a receptacle.
Connect to panel with correct size breaker.
Have instructor review finished connections.
Instructor will then “Power On” completed circuit to allow for circuit testing.
Answer all questions for this lab listed below.

Questions
: State the CEC rule number if the code book is used.
1.
Would the circuit still work if you used the white wire for power and black for neutral?
Definitely yes, the Circuit will work properly because both conductors are the same from the inside, only difference is the color of the insulation. However, it will be an unsafe practice and it also violates electrical standards. It may also mislead another installer. 2.
List another name for the identified conductor?
Identified conductors can also as ground circuit conductor or neutral.
3.
Why are the terminals of the lamp holder colour coded?
Because it helps you to match each wire to the correct terminal. In that holder center is for hot wire and the outer one is for neutral. 4.
What are the distances NMSC cable need to be supported (stapled) when run between boxes
according to the CEC? Show the Code Rule.
As per rule 12-510(2) in the electrical code book, we should give support to the conductor after every 1.5m from the junction box to the destination. 5.
Which conductors (hot, ground or neutral) are always connected to the light switches?
we connect the hot wire to the light switch to open and close the circuit.
