The Conversions Tech Series 100 is a single-gang weather-tight enclosure designed for outdoor and industrial electrical installations. Built from A380 die-cast aluminum with a polyester powder-coat finish, this enclosure provides 18.3 cubic inches of wiring volume for switches, sensors, GFCIs, or receptacles. Three factory-tapped 1/2"-14 NPSM hubs (one back, two sides) enable flexible conduit routing, while the NEMA 3R/4 rating ensures protection against rain, dust, and hose-directed water. Common applications include HVAC disconnects, industrial controls, and commercial exterior power distribution.

FAQ
What conduit sizes does this enclosure accept?
The three factory-tapped hubs accept 1/2"-14 NPSM threaded conduit. The O-ring seal design requires 3-1/2 turns engagement minimum, with lock-nuts torqued to 35 lbf·in for weather-tight termination.
Is this enclosure compliant with NEC box fill requirements?
Yes. The 18.3 in³ internal volume complies with NEC 314.16(A) for standard device configurations. Verify conductor counts and device volumes against Article 314 for your specific installation.
What torque values apply during installation?
Mounting lugs: 25 lbf·in. Ground screw: 12 lbf·in. Device mounting to 6-32 bosses: 8 lbf·in. Closure plugs with nitrile gasket: 30 lbf·in. Post-installation meg-ohm test should exceed 100 MΩ at 500 VDC.
