Equipment ConnectionsV139 audit-polished route

Confirm the manufacturer/project connection point before drilling or fastening to an equipment cabinet. Watch for coils, controls, wiring, drain pans, access doors, filters, and service space.

Open in Field Rescue Open category

Field checklist

Find the approved connection flange, frame, collar, or adapter point.
Check whether fastener length/depth is limited by manufacturer instructions.
Look for coils, wiring, controls, insulation, drain pan, or moving parts behind the panel if permitted.
Keep doors, filters, disconnects, control panels, actuators, and coil pull space clear.
Ask before drilling into any casing that does not have an obvious approved connection point.

Ask foreman

Before I fasten duct to this cabinet, can you verify this is the approved connection point and fastener depth?

Do not

Do not drill into equipment casing because it looks like normal sheet metal.

Why it matters

Equipment cabinets can hide expensive parts right behind thin metal. A wrong screw can damage controls, coils, wiring, or drain pans.
