Abstract
Abstract A dead front system provides fluid access to an electrical connector and cable. The dead front system includes an injection plug, a fluid access system, and a tube connected at a first end to the injection plug and at a second end to the fluid access system. The injection plug, fluid access system, and tube are surrounded by a conductive, grounded surface.
