Making life in the field EASIER and SAFER
WE make a GREAT CONNECTION.

NSi's offering of mechanical connectors is more than complete – single, double, panelboard, solderless, stacked & terminal lugs, and that's only the beginning.

Polaris™ insulated splices were the original insulated splice; for the last few decades, Polaris has served electricians by developing a Polaris with every port and entry configuration the market could ask for. And if the splice you need isn't listed, we can engineer a custom Polaris insulated splice for your job within days.
