opinions please
doing a rewire of a factory/ workshop where i work. just about figured out how im going to do it ( been a ball ache because trying to keep downtime down
)
theres a possibility though i may have to joint some big swa. current setup is some 120mm 4 core feeding a Db. Im scrapping the db and hoping to move the circuits to other boards. with the cable i have left over (the 4 x 120mm) im then hoping to use it to power a big welding set (100 Amp per phase ).
only problem is its not long enough so i will need to get some more swa and join it.
1,the origanol swa is from a busbar chamber and doesnt have an isolator so i obviously need one in. my idea was to use an isolator to join the cables ( solving 2 problems at once) opinions on this???
so, busbar chamber-swa (4 x 120mm)-isolator-swa (?)-welding set.
2, i havent done the calcs yet but im thinking the new swa wont need to be 120mm, can anybody see a problem if i make the swa smaller from the joint onwards (obviously itd be fused for the second cable)
3, whats peoples thought on the isolator, protection being in the middle of the run? suppose in a way its still protected.
cheers in advance.
