Outage Rotation Reality
Insulators follow the outage circuit — spring and fall plant shutdowns mean 6-day weeks at 1.5× and 2×.
- • Outage hours past 40/week → premium deductible
- • 2× Sunday premiums: premium portion above base counts
- • Track your W-2 OT boxes; employers won't break out premium until 2026 W-2s
Worked Example
Single insulator, $27/hour, 420 OT hours.
