Why electrical workers' comp is tricky in Wisconsin

Electricians often perform low-voltage work (security, AV, telecom) which has its own class code at lower rates (5191). Properly splitting these can save significant premium.

Tips for Wisconsin electrical contractors

• ✓ Document low-voltage vs power wiring split — 5191 is much cheaper than 5190
• ✓ Maintain OSHA 10/30 training records for arc flash and lockout/tagout
• ✓ Outside line work (utility) is class 7601 — different rates
