I am writing out a brief guideline for electrical practices in a warehouse area that is Class 1 Div 2. I just wanted to make sure I'm not missing any area. The goal is to not overbuild this place and have Class 1 Div 1 practices where Class1 Div 2 would be fine.
Let me know if any further information is needed and/or if this guideline seems up to snuff with you guys.
As always thanks for posting :smile:
THIS SPEC CLARIFIES NEC 2005 PRACTICES ON CLASS 1 DIVISION 2 AREAS. ANYTHING NOT COVERED IN THIS SPEC SHALL AT THE MINIMUM COMPLY WITH THE 2005 NEC.
Light Switches: Must be in an explosion proof enclosure and sealed according to 501.15B and E. Wiring methods must comply with 501.10B.
Light Fixtures: If rated for Class 1 Div 2 can be wired with standard jboxes etc so long as the wiring method complies with 501.10B and E.
*Regarding 501.10B4 in the blue comment section they mention "lighting outlets" what exactly does that mean? Is it an outlet labeled specifically for only lighting applications?*
Receptacles: Must be Class 1 Div 2 and sealed according to 501.15B and E. Wiring methods must comply with 501.10B.
Fire Alarm Strobes, Pulls, Horns, and Audible Strobes: If rated for Class 1 Div 2 can be wired according to 501.10B. However if they are not they must be Class 1 Div 1 rated and be enclosed in explosion proof boxes and sealed according to 501.15B and E. Wiring methods must comply with 501.10B.
Additional Seal Locations: Immediately after leaving the Class 1 Division 2 location all conduits must be sealed according to 501.15B prior to any other conduit separation.
Let me know if any further information is needed and/or if this guideline seems up to snuff with you guys.
