ASSIGNMENT # 1
PART1
Direction: These numbers of Air-Conditions; 9,000BTU, 12,000BTU, 18,000BTU and 24,000BTU, Select from among these. Connect
and install 2ACs in working condition.
Use 2 terminals running capacitor (RC) and one fan capacitor (FC) for one.
For the other, use 3 terminals running capacitor (RC). Use one 2 circuit panel box for each AC.
Show the sizes of Breakers, Conductor Number, Empty Amperage, Full Load Amperage, and AC Receptacle Fuse Amp Number.
Color Code Your Work, Use Scales.
PART 2:

List 10 needed Materials for each job among thousands

List 10 tools for these jobs
ASSIGNMENT # 2
PART 1:
1. Connect the compressor with two (2) terminals running capacitor only, show power source N&P1.
2. Connect the fan with three (3) terminals running capacitor only. Show power source N&P1.
3. Connect the AC fan with fan capacitor only. Use two (2) circuit panel boxes in working condition. Explain the
diagram
4. Name the eight methods according to our studies, when a compressor is not good.
5. Name five safety rules as a technician.
PART 2:
1. We agreed that if the compressor loses suction it will not pump well yes, and it will not suck well yes. But tell me what
will happen?
