Emergency lighting systems are essential in providing illumination during emergency situations such as power outages or fire outbreaks. In this article, we will be discussing the B50 emergency ballast wiring diagram, which is one of the most popular emergency lighting systems used in commercial and industrial settings.
What is an Emergency Ballast?
An emergency ballast is a device that is used to provide backup power to lighting fixtures during an emergency situation. It contains a battery that is charged when the power is on, and when the power goes out, the ballast activates the battery to provide power to the lights.
The B50 emergency ballast is a type of emergency ballast that is designed for use with fluorescent lighting fixtures. It is a reliable and efficient emergency lighting system that provides backup power for up to 90 minutes.
B50 Emergency Ballast Wiring Diagram
The B50 emergency ballast wiring diagram is fairly simple and straightforward. The ballast is wired in between the AC power source and the fluorescent lighting fixture. When the power is on, the ballast charges the battery and powers the lighting fixture as usual. When the power goes out, the ballast activates the battery to provide backup power to the lighting fixture.
Below is a step-by-step guide on how to wire the B50 emergency ballast:
| Wire Color | Function |
|---|---|
| Black | AC Power |
| White | AC Neutral |
| Red | Unswitched AC Power |
| Blue | Switched AC Power |
| Yellow | Fluorescent Lamp |
| Orange | Battery Positive |
| Brown | Battery Negative |
Step 1: Turn Off the Power
Before you start wiring the B50 emergency ballast, you need to turn off the power to the lighting fixture. This is to prevent any electrical shock or injury while working with the wiring.
Step 2: Locate the Wiring Connections
Locate the wiring connections between the lighting fixture and the power source. You should see four wires – black, white, red, and blue. The black and white wires are for the AC power supply, while the red and blue wires are for the switching function.
Step 3: Connect the Ballast Wires
Connect the ballast wires to the corresponding wires on the lighting fixture. The yellow wire should be connected to the fluorescent lamp, while the orange and brown wires should be connected to the battery positive and negative, respectively.
Step 4: Test the System
Once you have connected all the wires, turn on the power and test the B50 emergency ballast system. Switch off the power to simulate an emergency situation and see if the ballast activates the battery to provide backup power to the lighting fixture.
