The Multiquip 81120 Earth Lead is a genuine OEM Earth Lead designed for ST4, ST6, ST41230, ST41460, ST61230, and ST61460 submersible pump models. As a factory-sourced component, this part meets the exact specifications required for safe and correct electrical grounding on your Multiquip submersible pump. Stocking the 81120 as a service spare keeps your pump running to spec and ready for the next job. Confirm your model code against the fitment list before ordering to ensure a correct match.
Key Features
- Correct Grounding Conductor Spec — Manufactured to OEM electrical specification, ensuring the correct conductor gauge and termination type for safe ground continuity in submersible pump applications.
- Drop-In Replacement — Engineered to connect directly to the original grounding points on supported models, matching the factory routing and termination without alteration.
- Broad ST-Series Fitment — Compatible with ST4, ST6, ST41230, ST41460, ST61230, and ST61460 submersible pump models, covering both the standard and dual-voltage variants in the ST family.
- Maintains Electrical Safety Integrity — A properly functioning earth lead is critical for operator protection; a damaged or missing ground conductor creates a shock hazard and can cause pump failure or electrical faults.
- Genuine OEM Quality — Sourced directly through Multiquip, the 81120 is built to the same standards as the original component installed at the factory — no guesswork on material grade or conductor rating.
The earth lead — also referred to as a ground wire — provides the essential electrical grounding path between the pump motor housing and the power supply's ground terminal. This connection protects operators from electric shock by giving fault current a safe route to ground rather than through the person touching the equipment. In submersible pump applications, where the unit operates in or near water, a sound earth lead is not optional — a worn, corroded, or broken ground conductor compromises electrical safety and may also trigger ground fault protection devices, shutting the pump down unexpectedly.
