There are two primary types of Saf-D-Grid Connectors, the 300VAC and the 400V options. The Saf-D-Grid 400V is often used in the capacity of power cables. Each type has its own respective design that cannot be cross-connected to access power from the other type. This superior design allows for the connection points to be concealed to prevent any arching or electrical shorts, while also preventing any male-to-male short circuit connections from occurring.
