The GenInterlock.com device is designed to provide a safe and compliant method for connecting a portable generator to a home's electrical panel, specifically for GE-200HDA MIRROR panels with a 150 or 200 amp single-handle vertical throw main breaker. Its primary function is to prevent the main utility breaker and the generator breaker from being simultaneously in the "ON" position, thereby eliminating the risk of backfeeding the utility grid, which is a dangerous condition for utility workers and can damage electrical equipment. This interlock system ensures that only one power source (either utility or generator) can be active at any given time, adhering strictly to National Electric Code (NEC) regulations.
The device operates on a mechanical interlock principle. When the main utility breaker is in the "ON" position, the interlock physically prevents the generator breaker from being moved to the "ON" position. Conversely, when the generator breaker is "ON," the interlock prevents the main utility breaker from being turned "ON." This mechanical safeguard is crucial for maintaining electrical safety during power outages when a generator is in use. The design is specifically tailored for panels where the spacing between the main breaker and the first adjacent breaker is 2 ½ inches, and it utilizes the top right side's two positions for the generator breaker.
Installation of the GenInterlock.com device involves several steps that emphasize precision and safety. The process begins with disassembling the interlock and using the bottom plate to mark drilling locations on the panel cover, ensuring accurate placement relative to the top left breaker. Before any drilling, the main breaker must be turned off, and the panel cover removed to prevent accidental electrical contact. Drilling the marked holes requires a supplied 3/16 drill bit, and it's essential to remove all burrs from the drilled cover to ensure a smooth fit and prevent interference with the interlock's movement.
Once the holes are prepared, the interlock plates are assembled onto the panel cover. Screws are inserted from the rear of the cover, followed by the installation of the bottom plate and then the slotted top plate. Thread lock is applied to the screws, and retaining nuts are installed to secure the assembly. A critical step here is to ensure proper movement of the interlock mechanism after assembly, confirming that it slides freely and without obstruction. This check is vital for the device's reliable operation.
Following the interlock assembly, a 2-pole generator breaker is installed in the top right side positions of the electrical panel. A "Generator Warning Sticker" is then placed on the generator breaker to clearly identify its function and associated safety warnings. This visual cue is important for anyone operating the panel.
Further installation steps involve securing the wiring and labeling. Zip ties are used to create a loop and are installed around the top set of breakers in the panel. These zip ties are pulled tight around the breakers to secure them, and any excess is trimmed. A warning label is then affixed next to the release tab on the zip tie at the generator breaker, providing immediate safety information to the user.
After the physical installation, the panel cover is re-installed, and a thorough verification of the interlock's operation is performed. This verification is a critical usage feature, ensuring that the device functions as intended. The user must confirm that when the main breaker is "ON" and the generator breaker is "OFF," the generator breaker cannot be turned "ON." Conversely, when the generator breaker is "ON" and the main breaker is "OFF," the main breaker cannot be turned "ON." This dual-check confirms the interlock's effectiveness in preventing simultaneous power sources. The manual explicitly states that if the interlock does not function properly, the device should not be used, and the manufacturer should be contacted immediately.
Finally, for user convenience and safety, a "Generator start-up procedure label" and a "CAUTION label" are placed on the panel box. An additional CAUTION label is also placed on the electric meter pan. These labels provide clear instructions and warnings, guiding the user through the safe operation of the generator and the interlock system.
Maintenance features for the GenInterlock.com device are primarily focused on ensuring its continued proper function and adherence to safety guidelines. The manual emphasizes that "Only qualified personnel should be working on the panel box" and that "An amateur should NEVER open the panel box." This highlights the importance of professional handling for any maintenance or inspection. The device is designed to be a durable mechanical solution, and its proper movement should be periodically checked. If the panel cover is ever removed, the generator breaker should never be able to be turned on, serving as an additional safety check for the interlock's integrity. The manufacturer explicitly states that if the interlock does not function properly for any reason, the system should not be used, and support should be sought. This proactive approach to maintenance and safety ensures that the device continues to provide its intended protection against hazardous electrical conditions. The disclaimer further reinforces that the manufacturer is not responsible for misuse or improper installation, underscoring the user's responsibility to ensure proper installation and maintenance by qualified personnel.
