In general, the insulation thickness for the same or greater voltage/amperage usage has decreased in thickness over the decades. That said, even while requiring "plenum grade" or similar low toxicity combustion producing materials, the vartious wires, cables do not need as much volume as what they are replacing. that said, they should not be a clearance issue IF carefully installed. When all of the wiring is replaced, and in the bargain much brighter LED tubes for future maintenance convenience, proably the old crumbling'bench' should be removed and replaced with new concrete to maintain the integrity of the tunnels. |
