NEMA 1 / 3R / 4 / 4X & Custom Enclosures
Standard and Custom Electrical Enclosures for Any Environment.
Spike Electric designs and fabricates electrical enclosures that protect equipment indoors or outdoors, in ordinary or hazardous (classified) locations. Choose from more than 100 standard sizes or a fully custom-built enclosure — across a wide range of NEMA ratings and materials — with fast lead times and in-house drilling, tapping, machining, and finishing.
PowerClad supports both new construction and the replacement of older air-break, minimum-oil, or SF6 switchgear — providing higher insulation levels in less space and reducing overall switchgear footprint for significant space savings.
