Nimbus | Pre-Insulated Electrical Connectors




NIMBUS from ILSCO is the industry leader of pre-insulated connectors, offering the broadest selection of products to meet any electrical need. The offering includes in-line, multi-tap, single, double, or multi-side entry, mountable, for motors, and high-density 2X for both code and flexible conductors.

ILSCO's NIMBUS insulated Aluminum 250 kcmil 3 to 14 port connectors are the first in the industry to be certified to ASNI C119.6 by UL and compliant to NEC 230.46 - suitable for use on the line side of service equipment.

The NIMBUS®4Flex series is flex-rated and affords the ability to mix ANY conductor class and ANY conductor material. Easily identified with blue caps, the offering has a patented screw design. Each screw has an integrated locking washer that eliminates the need for ferrules, improves vibration resistance, and compresses the flexible conductor strands without damage. This unique mechanical screw is the first to be UL Listed and CSA Certified for all six classes of flexible conductors (G, H, I, K, M & DLO)
