Buying Guide
What to consider when choosing a generator inlet box
- Amperage and voltage needs: Match the inlet box to your generator’s output and your transfer switch or load center’s requirements. Higher amperage (50A) supports more circuits; 30A is often enough for essential loads.
- Pre-drilled holes vs. drilling needs: Pre-drilled designs save time and reduce the risk of misalignment. If you anticipate changing layouts, a pre-drilled, multi-direction setup is advantageous.
- Outdoor durability: Look for ETL or equivalent certification and weatherproof enclosures (3R or better) to withstand rain, dust, and temperature changes.
- Indicator features: A LED or indicator light helps confirm a secure connection, especially at night or under inclement conditions.
- Cord length and compatibility: Ensure the cord length accommodates your installation distance and that plugs are compatible with your generator and transfer switch.
- Safety considerations: Ensure there is no risk of backfeeding or improper bonding to the home system. Follow local electrical codes and install via a qualified technician if needed.
Frequently Asked Questions
- What is a generator inlet box used for? A generator inlet box provides a safe, weatherproof connection point between a portable generator and a home’s electrical system or transfer switch.
- Do these boxes require professional installation? Installation should follow local codes; many users install themselves if they are comfortable with basic wiring, but professional help is recommended for complex setups.
- What amperage should I choose? Choose based on your essential loads and the transfer switch’s rating. 30A is common for smaller setups; 50A suits larger homes or more demanding circuits.
- Are ETL-listed products safer? ETL listing indicates compliance with safety standards and is generally preferred for outdoor electrical equipment.
- Can I mix brands of cords and inlet boxes? Yes, as long as the connectors (NEMA types) are compatible and meet your system’s requirements.
- What if I need a longer cord than included? Many kits offer longer cords separately or as part of a kit; verify compatibility with the inlet box and your generator.
