The Wacker Neuson Receptacle Socket is a genuine OEM component designed for the HI 770 XHD series indirect-fired diesel air heaters, including Arctic Bear XHD and HI770XHD configurations. As a direct factory replacement, this socket installs into the heater's electrical system exactly as the original, with no adaptation needed to restore proper function. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the components that left the factory, ensuring consistent fit and dependable operation in demanding heating applications. Confirm your machine model and machine number before ordering to ensure is the correct socket for your specific unit.
Key Features
- Correct Electrical Specification — Genuine OEM construction ensures the socket meets the exact contact rating and connector geometry required by the HI 770 XHD electrical circuit.
- Direct Factory Replacement — Connects to the heater's wiring harness at the original mounting point, restoring the electrical interface without rework or adapter fittings.
- Broad HI 770 XHD Compatibility — Fits Arctic Bear XHD and multiple HI770XHD build variants, covering 2x12, 1x16, and 1x20 output configurations as well as Extra Heavy Duty Air Heater models.
- Sustained Heating Output — A sound receptacle socket maintains the uninterrupted electrical connections the heater depends on; a corroded or damaged socket can cause intermittent operation or complete heater shutdown in cold-weather conditions.
- Electrical Safety Integrity — In a diesel-fired heating system, a properly rated OEM socket is essential to prevent arcing, heat build-up, or unintended circuit faults at the connection point.
The receptacle socket is an electrical connector mounted within the HI 770 XHD indirect-fired heater's control and power circuit. It provides the secure plug-in interface that links key electrical components — such as controls, ignition circuits, or power feeds — allowing current to pass reliably through the system. When the socket becomes worn, corroded, or cracked, the connection can loosen or fail entirely, causing the heater to operate erratically or not start at all. Replacing a faulty socket with the correct OEM part restores the solid electrical contact the heater needs to deliver consistent, full-output heat on the jobsite.
