  • 【Installation Made Easy】 No Drilling Required – Designed to solve the frustration of drilling through thick metal. Unlike traditional boxes, this inlet box features 4 pre-punched removable knockouts (Left, Right, Bottom, and Back). You can simply pop them out with a screwdriver and hammer to run your conduit. This straightforward design, combined with the removable front panel, makes wiring significantly faster and easier for both DIYers and professional electricians.
  • 【Generous Interior Wiring Space】 – Struggling with stiff 10-gauge wires is a thing of the past. Our upgraded housing offers 50% more internal room than standard compact boxes. This "Larger Space" design facilitates better heat dissipation and allows for comfortable maneuvering of 10 AWG wires, ensuring a secure, stress-free connection without pinching or damaging the insulation during setup.
  • 【Product Size】14.2 in (L) x 3.5 in (W) x 7.1 in (H), The depth of the lid is 2.6 inches.
  • 【NEMA 3R Weatherproof Outdoor Enclosure】 – Engineered to withstand harsh outdoor elements. Constructed from heavy-duty galvanized steel with a corrosion-resistant powder coating, this box is rated NEMA 3R for rain and ice protection. The slanted clamshell cover effectively deflects rain away from the plug pins, and the bottom inlet design ensures water cannot pool inside, keeping your power connection dry and safe during storms.
  • 【30 Amp Power Input Specification】 – Features a standard NEMA L14-30P inlet plug (Male) rated for 30 Amps, 125/250 Volts, and up to 7500 Watts. It is designed to connect a 4-prong generator extension cord to a manual transfer switch or interlock kit, facilitating power transfer to a breaker panel during outages.
  • 【ETL Listed & Safety Features】 – Tested and certified by Intertek (ETL) to meet North American safety standards. The unit includes a visible green grounding screw to ensure proper grounding connection. The flip-lid is designed to be lockable (lock not included) to prevent unauthorized access when not in use.
