Well you can stand a shot of secondary like 240 but usually you tie up with a primary line you either get cooked or die .There are exceptions for the lucky ones .
BTW Toms brother in law is the the tree bizz also .Last summer one of his idiots put the lower boom of a two year old Altec into the primary .Did like 40 thousand dollars worth of damage .Took all the lines ,fried the rotate bearing ,hydraulic pump ,all the electrics and set the damned thing on fire .Blew the primary fuse .The operator didn't get hurt thank heavens but he also doesn't work there any more either .
I think they had to replace the whole lower boom .
