Class Code 3569
Electric Motor Mfg Or Repair
Class Code 3569 covers businesses that manufacture, rebuild, rewind or repair electric motors and their components. The approved California pure premium is $2.236 per $100 of payroll, a baseline insurers use to price expected loss costs for these operations.
What Class Code 3569 Covers
This classification applies to shops and field services that disassemble, rewind, re-insulate, repair armatures/rotors, rebalance shafts, install bearings, and perform electrical testing on motors. It includes both light manufacturing of small motors and heavy industrial motor repair work such as rewinding large AC/DC motors, replacing commutators, machining components, and varnish/oven drying operations. Work performed in a dedicated repair shop and on-site motor rebuilds at customer facilities are both within scope when employees of the reporting employer do the work. Routine motor maintenance tied to general building maintenance—where electricians only replace but do not rewind or rebuild core components—may be classified elsewhere, so accurate payroll allocation is important.
Who It Applies To
- Motor rewind and repair shops that rewind coils and rebuild armatures
- Industrial maintenance shops that perform full motor restorations
- OEM shops manufacturing small electric motors and subassemblies
- Field service technicians who disassemble and rebuild motors on customer sites
- Machine shops that machine shafts, keyways, and commutators as part of motor repair
Common Job Duties
- Disassemble and inspect stators, rotors, armatures, and commutators
- Strip and rewind coils using winding machines and hand winding
- Apply insulation, bake/varnish coils, and cure in ovens
- Machine and recondition shafts, commutators, and bearing housings
- Dynamically balance rotors and perform high-voltage electrical testing
- Operate hoists/cranes to lift heavy motors and perform field reinstallation
Common Injury Risks
Understanding the $2.236 Rate
The pure premium of $2.236 per $100 of payroll represents the insurer's estimate of expected claim costs for the classification before expenses and profit. Insurers multiply this rate by your payroll for employees assigned to 3569 to compute base loss cost; the final policy premium then includes insurer expense loads, state assessments, your experience modification, policy credits or debits, and any schedule rating or deductible adjustments.
Cal/OSHA Compliance Requirements
Key Cal/OSHA topics for motor manufacture and repair include control of hazardous energy (lockout/tagout) during disassembly and testing, electrical safety and arc-flash protection when performing live tests, machine guarding for lathes and grinders, hazard communication and respiratory protection for varnishes and solvents, and hearing conservation where noise exceeds limits. Employers must provide written programs, employee training, appropriate PPE, and maintain required injury records and reports.
How Key HR Helps Employers Under Class Code 3569
A PEO like Key HR helps employers under Class Code 3569 by ensuring accurate payroll classification, delivering targeted safety training (electrical safety, LOTO, respirator use), implementing return-to-work programs to shorten claim durations, and handling centralized claims management and loss-control inspections. Key HR's group purchasing and safety resources can reduce frequency and severity of claims, which helps lower your experience modification and overall workers' comp costs.

How do I know whether my employees belong in Class Code 3569 or another classification?
Use the actual work performed: 3569 applies where employees rewind, rebuild, machine, balance or electrically test motors and armatures. If staff only install or replace complete motors without rebuilding components, a different maintenance or electrician code may apply. Keep detailed payroll records and consult your carrier or PEO at audit time to ensure proper allocation.
What practical steps reduce workers' comp costs for motor repair operations?
Implement documented LOTO and electrical safety programs, train staff on arc-flash and PPE, use mechanical hoists for heavy lifts, control solvent exposures with ventilation and respirators, enforce machine guarding, and run a formal return-to-work plan. Reducing claim frequency and severity lowers your experience modification and future premiums.
Are field service technicians who rewind motors at customer sites included in this class?
Yes, employees of your company who perform rewinds or rebuilds at customer locations are generally reported to 3569. Accurately tracking hours worked in-shop versus on-site and distinguishing employees from subcontractors is critical for correct classification and premium calculation.
