Equipotential safety device
View Patent ↗An equipotential safety device comprises a metallic grate sized and configured to be set upon the floor of a bucket of a bucket truck. The grate is in electrical communication with an electrical grounding source.
1 . An equipotential device comprising:
a grate configured to be positioned within a bottom of a basket of an aerial lift vehicle, the grate including a grounding stud disposed at a corner of the grate;
a dielectric liner positioned beneath the grate within the basket;
a bonding cable having a first end and a second end, the bonding cable comprising a copper stranded cable;
an attachment clamp connected to the second end of the bonding cable, the attachment clamp configured to secure a low-resistance connection to a specific conductor of an overhead power line; and,
a low-resistance connection attaching the first end of the bonding cable to the grounding stud; and,
wherein, when the attachment clamp is connected to the specific conductor, the grate, the bonding cable, the attachment clamp, and a lineman standing within the basket form an equipotential loop with respect to the specific conductor to reduce a voltage differential to approximately zero volts.
2 . The equipotential device of claim 1 , wherein the bonding cable has a diameter of approximately 1/0 AWG and a length of approximately twelve feet.
