We only work up to 44kv, so I can only tell you what we do on this voltage. Only journeyman & the work is very limited we only cut in or sleeve out switches. there is not the clearances to install deadends. If you are going to start barehanding you should hire a good trainer to come in house & do some jobs at your site. All of our barehand buckets are bonded from the manufacter for barehand work, not all bucket trucks have everything bonded at the buckets. All of our barehand trucks are also dielectrically tested every 6 months, & we always do a metered current leakage test prior to commencement of the job, also the bonding leads & clamps & grids are only used to keep the end of the boom at line potential & ther length should not be longer than the depth of your bucket. We have been doing this work before I started & I have been here over 20 years & we have had no problems. The work comes in spurts. The largest cover up we have is rated at 46 kv so we can not rely on it for brush contact on other energized conductors we must maintain our clearances. This is just covering some of the real basic stuff, the main things are to maintain your clearance & use proper jumpers that we install with sticks before we bond on & you have to have a dedicated observer who has no other duties. It is the best way to work live, but for us the work is very limited.
