HOW TO CONNECT CEILING LAMP TO BE "LIVE" AT ALL THE TIME?

LESSON NO. 4

TOPIC:-   Wiring Methods.

AIM:-    How to connect ceiling lamp to be "LIVE" at all the time?


PERFORMANCE OBJECTIVES:-   S.W.B.A.T  (Student will be able to)

1. Define power source.
2. Identify the main conductors in an electrical circuit.
3. Connect a lamp to be "LIVE" at all the times.

DEFINITIONS:-   POWER SOURCE:-   It is the main component in the circuit. This is where every circuit start.

CONDUCTORS IDENTIFICATION:-   HOT WIRE:  Also knows as the feed wire, it is responsible for supplying the positive part of the power to an electrical circuit. It is drawn as a solid line.

THE NEUTRAL WIRE:-    This is the conductor which returns power supplied by the "HOT" wire in a circuit to any given loads. The neutral wire either white or gray.

THE GROUND WIRE:-    This is the wire which is responsible for protecting life and property this color is "GREEN".

HOW TO MAKE A BOX OFFSET BEND?

LESSON NO. 3

TOPIC:    EMT (Electrical Metallic Tools)

AIM:     How to make a Box offset bend?

PERFORMANCE OBJECTIVES:     S.W.B.A.T. (Student will be able to)

1. Define a box offset bend.
2. Know the required steps to make a box offset bend.
3. Make a box offset for 1/2" inch EMT.

DEFINITION:   BOX OFFSET BEND :-   It is a bend made on a piece of tubing at a box entry point. This bend is made to allow proper support to the tubing through it entire run. By keeping the tubing flush with the surface and rising up only at the desired K.O. entry point.

TOOLS:     A 1/2 inch EMT bender is to be used or a special offset bender.

STEPS: 

1. Insert the tip of the tubing in the EMT bender. 
2. Make a (15*) slight bend to the tubing.
3. Make your bend to face down and re-inserted into the bender.
4. By pass the 1st bend with the arrow on the bender and make your 2nd bend (15*). 
5. Test your completed offset bend on a flush surface.

 

REVIEW SAFETY GUIDANCE FOR ELECTRIC WORK

TOPIC: Wiring Methods

AIM: How to install an electrical device in an existing construction?

PERFORMANCE OBJECTIVES: S.W.B.A.T.

1. Define a device Box.
2. Know where is installed.
3. Know the necessary steps to install it.

DEFINITION:
Device box gang box that is used for the installation of switches, lamps, single and duplex receptacle. It is used in finished construction, where all walls, floors and ceilings are closed in.

STEPS:

1. Measure the distance at the desired location.
2. Make out the box on the wall or ceiling using a pencil.
   
3. Use a key-hole saw to cut out the wall.
4. Insert the cable into the box K.O. clip.
   
5. Insert the box into the hole.
6. Fasten the box using Erickson or Madison clips on each side.
