Porta-Safe® Temporary Power Specs

Because each job site is unique and has specific requirements, we custom build Port-Safe to meet those exact site requirements for your temporary power needs.

All Porta-Safe® Load Centers are constructed according to the following standards that differentiate our design from all others. These innovations have evolved over many years as a result of input from electrical engineers and our engineering staff.

Enclosure:
All Porta-Safe® units shall have an integral custom enclosure including transformer, breaker panel, etc., designed to the specified NEMA standard. An external panel or boxes bolted to transformer will be unacceptable. All steel surfaces shall be chemically cleaned, primed and painted with (2) two coats of ASA-51 epoxy paint.

Stitch welds 1" in length every 6" will be used on non-structural parts. Units shall be provided with adequate lifting means. On the four wheel cart, the caged design shall have a square tubular frame with an internal threaded rod running the length of the risers, also included are lifting eyes that are threaded and welded. All receptacles, breakers, lights and switches shall be recessed from cage to prevent damage. An SO cord storage compartment shall be provided on top.
