Shelter Electrical Packages

  • 12 gauge THHN wiring in rigid Schedule 40 PVC conduit
  • 125 A main lug load center
  • 20 A GFCI outlet with in-use weather cover
  • Exterior duplex switches for independent control of interior light and fan

For most users, this equipment is sufficient to meet their needs, but for those that need something more, Openchannelflow offers a number of upgrades to the standard equipment.

Conduit

The standard electrical conduit in Openchannelflow fiberglass equipment shelters is rigid Schedule 40 PVC.  Like everything else in our shelters, the standard conduit can be modified or customized:

  • Schedule 80 PVC
  • Electrical metallic tubing (EMT)
  • Galvanized rigid conduit (GRC)
  • PVC coated galvanized rigid steel

Load Centers

  • Convertible main lug or main breaker configurations
  • Single or three-phase
  • 125 to 225 A ratings
  • NEMA 1 or NEMA 3R enclosures

Where specialty load centers are required, Openchannelflow also offers integration of load centers from GE and Siemens.   

Outlets

Leviton GFCI outlet with weather cover mounted in fiberglass equipment shelterThe Openchannelflow standard electrical outlet in our fiberglass shelters is a 20 A GFCI with in-use weather cover.  

While one GFCI is part of the standard equipment package, additional GFCIs and specialty outlets are available for mounting inside (or outside) the shelter.

Switches

Additional switches are available for independent control of exterior lights, for three-way control of the interior lights, and as disconnects for circuit power.

Wiring

12 gauge stranded THHN is the standard wiring for Openchannelflow fiberglass equipment shelters.  Where necessary (typically to heaters and larger HVAC units), larger sized wiring can be provided.
