Key Features

• Genuine OEM Electrical Isolation: — Manufactured to Multiquip's original dielectric and dimensional specifications, ensuring the correct insulating performance for this generator application.
• Drop-In Installation: — Engineered as a direct replacement that seats and secures exactly as the original, with no rework of surrounding hardware needed.
• Broad DCA and NGA Series Coverage: — Compatible with an extensive range of Multiquip ultra-silent and super-silent generator models across the DCA and NGA families, from DCA25SSI through DCA150-class and NGA150SSPUPL variants.
• Protects Electrical Components from Stray Current: — A functioning insulator washer isolates fasteners and conductive surfaces, preventing unintended current paths that can damage sensitive generator components or create hazardous conditions.
• Electrical Safety Compliance: — Proper insulation hardware is critical in generator assemblies where stray current or grounding faults can pose a risk to personnel and connected equipment; using the correct OEM part maintains original design intent.

An insulator washer is a non-conductive fastener component used in generator assemblies to electrically isolate bolts, studs, or mounting hardware from surrounding metal structures. By preventing direct metal-to-metal contact at fastening points, it stops stray current from traveling through the frame or enclosure where it does not belong. When an insulator washer degrades, cracks, or is replaced with an incorrect substitute, it can compromise the generator's electrical isolation, leading to grounding faults, component damage, or unsafe operating conditions.
