As great as PowerCon connectors are, they have one potentially serious flaw. They can’t be connected “under load”. That means that the device or piece of equipment that is being hooked up with a regular PowerCon equipped cable can’t be “on” when it is plugged in.
You can read more about that here.
The True 1 series of connectors has been designed to address this problem.
The sequence in which the conductors in a PowerCon True 1 make contact with their mating contact mean that you can connect under load without concern of arcing between two energized contacts.
