NEMA L14-30P Twist Locking to NEMA 5-20R T-Blade Power Adapter
This compact, direct-molded block-style power adapter (no flexible cable for minimal bulk) features a NEMA L14-30P male plug (4-prong twist-lock, standard on 30A generators for 125/250V output) integrated into four NEMA 5-15R/5-20R female receptacles (T-slot household outlets rated for 20A/125V, compatible with 15A or 20A plugs). It’s designed for safely distributing 110V/120V power from a single generator outlet to multiple devices, such as tools, lights, chargers, or appliances, in space-constrained setups like job sites, camping, emergencies, or RV events. The built-in 20A circuit breaker provides overload protection per outlet or total (model-dependent), automatically resetting to prevent damage from surges or imbalances. ETL Listed (Intertek certified) ensures compliance with UL 498 and UL 62 standards for grounding, impact resistance, and weatherproofing. Custom color options (e.g., black, yellow, red, or Pantone-matched) are available via OEM for branding or visibility. The no-cable design offers a secure, low-profile connection, ideal for direct generator-to-multi-outlet use without tangling.
Key Use Case: Plug the L14-30P male end directly into your 30A generator outlet, then connect up to four household devices to the 5-15R/5-20R outlets for balanced power distribution. Excellent for construction crews or tailgaters needing quick multi-tool access without extensions.

Important Usage Notes & Warnings:
- Total Load Limit: The combined load of all devices plugged into the adapter MUST NOT exceed the 20-amp rating of the internal circuit breaker. The maximum total power is 5000W at 250V or 2500W at 125V per leg.
- Proper Source Required: This adapter must only be plugged into a properly wired and grounded NEMA L14-30R receptacle on a circuit protected by a 30-amp breaker.
- Power Distribution: The L14-30 plug supplies two 125V legs. The four outlets are typically split across these two legs to balance the load. Consult the wiring diagram for specific configuration.
- No Daisy-Chaining: Do not connect this adapter to another power strip or adapter. This can lead to overload and fire hazard.
- Regular Inspection: Inspect the adapter before each use for any signs of damage, such as cracks, burns, or exposed wiring. Do not use if damaged.
- Professional Use Recommended: Installation and use should be performed by qualified personnel who understand electrical systems and load calculations.
