Abstract
A portable gradient control plate providing protection against touch potentials for electrical workers that can be carried and set-up at workplace conveniently. The gradient control plate has a perforated top plate for stability and extra foot grip minimizing slip hazards. It is supported by aluminum members thus elevating the foot above grade. The gradient control plate can be folded through hinges and equipped with a handle introducing portability into the apparatus. Each aluminum plate is secured by a locking mechanism and bonded by a braided copper wire to ensure equipotential between plates. Aluminum rods for attaching hotline clamps will be placed on each side of the gradient control plate for electrical connection to the power source.
