vhbw 50 Amp Generator Inlet Box NEMA SS2-50P — Weatherproof Housing with Built-in 50A Circuit Breaker, 5 Wiring Ports

The vhbw 50 amp generator inlet box is a weatherproof, ETL-listed power inlet with a built-in 50A circuit breaker and five wiring ports for easy, code-friendly connection of L14-50P to SS2-50R generator cords.

This inlet box is engineered for reliable emergency power connections where outdoor durability and straightforward wiring are essential. It accepts standard 50A generator plugs, houses a factory-installed circuit breaker to protect equipment, and provides multiple conduit entry points so installers can route heavy-gauge (4–6 AWG) conductors from any direction. The oversized interior space helps with wiring bends and connector placement while the NEMA 3R-rated enclosure resists rain, snow, and corrosion.

How does the built-in 50A breaker protect my generator and appliances?

The integrated 50 amp circuit breaker interrupts overloads and short circuits to reduce the chance of equipment damage during transfer operations. It eliminates the need for a separate external breaker at the inlet, simplifying installations and shortening run-time troubleshooting.

• Factory-installed 50A breaker protects both 120V and 240V loads.
• Protects generator and downstream appliances from overcurrent events.
• ETL listing verifies tested safety performance.

What makes this inlet box easy to wire in different installations?

Five pre-drilled wiring ports provide flexible conduit entry from the sides, top, bottom, or rear, accommodating site-specific run directions without added drilling. The generous internal cavity supports neat routing of 4–6 AWG conductors and gives space for connectors and strain reliefs.

• Five-port layout for multi-directional conduit and cable entry.
• Compatible with 4–6 AWG wires for 50 amp service.
• Roomy interior reduces crowding during installation and maintenance.

Is the enclosure durable enough for outdoor emergency use?

The vhbw inlet box meets NEMA 3R requirements, designed to withstand rain, snow, and exterior conditions common to standby power systems. Heavy-duty materials and corrosion-resistant finishes extend service life, even when exposed to the elements.

• NEMA 3R weatherproof rating for outdoor protection.
• Rugged construction resists rust and physical wear.
• Secure latch/closure keeps internal components dry and accessible.

Which cords and plugs are compatible with the SS2-50P inlet?

The NEMA SS2-50P male receptacle is designed to accept L14-50P to SS2-50R generator cord configurations and other standard 50A plugs of compatible form. This makes it suitable for powering home transfer switches, RV shore power systems, or portable transfer panels.

• Fits L14-50P to SS2-50R cords and equivalent 50A connectors.
• Supports 125/250V systems up to 12,500W (240V) maximum load.
• Ideal for transfer switches, inlet panels, and emergency power setups.

Who is this for: The vhbw 50 Amp Power Inlet Box is intended for electricians, contractors, and homeowners installing or upgrading standby power connections where durability, clear wiring access, and built-in overcurrent protection matter. It suits residential whole-house backup systems, RV or cabin power setups, and small commercial applications that need a reliable, code-friendly outdoor inlet with flexible conduit options and ETL-listed safety.
