Cable Disconnect under load Options?
« on: April 18, 2017, 07:12:45 PM »
Hi:  My apologies if a solution is posted - I did a quick search and did not find a solution already.
We are installing a portable battery/charge controller/inverter on a cart system to a fixed 1000W array.  Intent is to be able to
unplug the DC source from the panels, and transport the cart to power a portable display unit. 

Looking for a way to interlock disconnect such that load is broken before DC connector is removed.  Will be operated by non-technical
personnel, so instructions alone not sufficient, also requires approval by electrical inspection branch (Canada)

Initially looked at Meltric connector as best solution, unfortunately cannot be UL (CSA) rated for disconnect under DC load without one-of testing fee. 

Can look at DC Load break contactor with interlock to E-box cover, but if an existing commercial solution is out there, that would be preferable.

Many thanks!

Doug W.
