Commercial Switchgear Requirements
Standard: NFPA 70B & OSHA Electrical Safety
Joule Heating equation ($P = I^2R$) requires $\ge 40\%$ operating load ($\ge 50\text{--}75\%$ ideal) for at least 2 hours continuously prior to scan.
Wind causes convective surface cooling, washing out thermal signals ($\Delta T$). Aerial flights restricted to $<15\text{--}20\text{ mph}$.
All electrical load, environmental wind, and facility access requirements meet NFPA 70B guidelines. Site is optimal for thermographer dispatch.
If site conditions fail upon inspector arrival due to lack of load or access, a $250.00 fee plus mileage applies.
