What is the approved boundary for a main-circuit record?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Follow the approved site process for isolation, verification, and authorized work before inspecting a main path. The fact that a contactor is visible or has a recorded indication does not establish a safe condition for its terminals, connected load, stored energy, or related control sources. OSHA materials provide the general safety boundary, while the local procedure governs the actual activity. (<a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1910\/1910.147\" rel=\"nofollow noopener\" target=\"_blank\">OSHA energy control<\/a>, <a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1910\/1910.333\" rel=\"nofollow noopener\" target=\"_blank\">OSHA electrical work practices<\/a>)<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">State where the record starts. Identify whether it comes from an approved observation, a system event record, an authorised diagnostic step, or a labelled image.<\/p>\n<blockquote>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Important:<\/strong> Do not bridge terminals, force a mechanism, or repeat a command merely to obtain a main-circuit observation.
