Abstract

A power distribution module for use on mobile equipment is described in the present disclosure and can include a housing having a power input port and a plurality of output ports integrally formed with the housing and open to an outer surface of the housing. Each of the input port and the output ports are configured to receive and secure a connector that is pushed and locked into place, thereby sealing the connection. The power distribution module can be used to split a single power line into multiple lines connected to electrical devices mounted on a piece of mobile equipment.
