This procedure requires contact with medium
voltage components. To avoid shock hazards, lock
out incoming power before working on the
equipment. (See Power Lockout Procedure, page
5-3). Verify with a hot stick or appropriate voltage
measuring device that all circuits are voltage free.
Failure to do so may result in severe burns, injury
or death.
1) The power and ground bus splice kit can be found in a package
