Generator Interlock for a GE PowerMark Load Center: A Comprehensive Guide for Electrical Safety
Hey readers,
Are you looking to install a generator interlock for your GE PowerMark load center? Look no further! This comprehensive guide will walk you through every step of the process, from selecting the right interlock to wiring it up safely.
What is a Generator Interlock?
A generator interlock is a safety device that prevents backfeed from your portable generator into the utility grid. When the interlock is properly installed, it will disconnect the load center from the grid when the generator is running, ensuring that electricity does not flow back into the utility lines. This is crucial for the safety of utility workers and your own safety.
Types of Generator Interlocks
There are two main types of generator interlocks for GE PowerMark load centers:
Mechanical Interlock
A mechanical interlock is a physical device that locks the generator inlet breaker in the "off" position when the main breaker is on. This ensures that the generator cannot be accidentally turned on while the house is connected to the grid.
Electrical Interlock
An electrical interlock is an electronic device that uses a relay to disconnect the load center from the grid when the generator is turned on. This type of interlock is typically more expensive than a mechanical interlock, but it is also more convenient and easier to install.
How to Choose the Right Generator Interlock
The best generator interlock for your GE PowerMark load center will depend on your specific needs and budget. Here are some factors to consider:
- Type of generator: Some generator interlocks are only compatible with certain types of generators.
- Size of load center: The size of your load center will determine the amperage rating of the interlock you need.
- Features: Some generator interlocks offer additional features, such as surge protection or remote control.
How to Install a Generator Interlock
Installing a generator interlock is a job that should be performed by a qualified electrician. However, if you are comfortable working with electricity, you can follow these steps:
Step 1: Gather Your Tools and Materials
You will need the following tools and materials:
- Generator interlock
- Wire strippers
- Screwdriver
- Electrical tape
- Conduit (optional)
Step 2: Disconnect the Power
Turn off the main breaker in your load center and remove the cover.
Step 3: Install the Interlock
Follow the manufacturer’s instructions to install the interlock. Typically, this will involve mounting the interlock to the load center and connecting the wires.
Step 4: Connect the Generator
Connect the generator to the interlock using a heavy-duty extension cord.
Step 5: Turn on the Power
Turn on the main breaker in your load center and then start the generator. The generator will now be able to power your house safely without backfeeding into the utility grid.
Table: Generator Interlock Options
| Interlock Type | Features | Pros | Cons |
|---|---|---|---|
| Mechanical Interlock | Physical device that locks the generator inlet breaker in the "off" position | Simple and inexpensive | Inconvenient to use |
| Electrical Interlock | Electronic device that uses a relay to disconnect the load center from the grid | Convenient and easy to install | More expensive than mechanical interlock |
Conclusion
Installing a generator interlock for your GE PowerMark load center is an important safety measure that can protect you, your family, and utility workers. By following these steps, you can ensure that your generator is connected safely and correctly.
