In this how-to presentation we look at the incredibly important process of crimping MC4's, from correctly mating the inserts to the connectors, tools used to cut and strip the cable through to the crimping process.
We are looking at this in relation to commercial solar systems where the voltages regularly get up to around 1000 volts and more if talking about solar farms.
Cable bending radius is discussed, correct insert seating and tightening of the MC4 nut are all shown in detail as well cable identification issues that may arise from tired solar installers!
This is perfect for the solar electrical apprentice who has never made an MC4 connection all the way to the experienced professional wanting to brush up on their technique.
Enjoy.
