I am starting this thread so I will stop hijacking other peoples conversations in order to sell my step-start delay
There are a lot of opinions on how to apply power to the controller. There are safety considerations for both the equipment and people. If we can work out some generally agreed upon ideas here then I will consolidate them and put them in the WIKI.
Some of the questions I have seen asked are:
How many contactors to use and where to put them.
Precharge, what is it, why do I need it, how do I do it.
How do I apply HV to the controller?
Do I need an emergency disconnect?
Fuses, Circuit Breakers or both?
I think I have the answers to these questions, but am open to having my ideas adjusted by other's opinions and experience.
