Title: Lab 11-4: DC Parallel DC Relay, AC Light, and AC Buzzer - 2 Hour
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 11: Parallel Circuits

Introduction

This is the last AC parallel lab. Keep in mind everything you have done and learned about AC parallel so far.

Instructions

Watch the example video, and then perform the lab.

1. Follow the guidelines on the Lab Expectations page.
2. Print off the drawing template found at the start of Module 11. (If you cannot print the drawing, draw the template on a piece of paper.)
3. Write your initials in the "Drawn By:" section of the template drawing.
4. Write the date in the "Date:" section of the template drawing.
5. Write the lab number in the "Drawing #" section of the template drawing.
6. Write the title of the lab in the "title" section of the template drawing.
7. Legibly draw up the following schematic using the drawing template and drawing legend. (Note: Refer to AMAR-1200-01 - AC Amps Measurement.pdf and AMAR-1200-02 - DC Amps Measurement.pdf found in previous modules for examples on how to properly draw a schematic.)
8. Draw the 24VAC transformer.
9. Draw 24VDC Power Supply.
10. Draw a SPDT switch that energizes the 24 VDC relay. Wire an AC light to turn on with the NC contacts of the relay. Wire the AC Buzzer to energize with the NO contacts of the relay. The AC light and buzzer must come from the separate AC breakers.

 | Note! |
The 15-amp breaker should have a black wire running to Terminal 1 on the relay.
The 20-amp breaker should have a black wire running to Terminal 8 on the relay.

11. Label all wires with the appropriate color.
12. Wire up the circuit per your drawing.
13. Show that the circuit works.
