Ingo Posted September 8, 2018 Share Posted September 8, 2018 I need some clarity on the Quattro 48/5000 current capacity. The manual states 'Maximum feed through current (A) 2 x 100' but then there is an 'Auxiliary output (A) 50'. Can anyone shed some more light on the two statements? Can I assume the AC Out 2 is also called the Auxiliary output and that is rated only at 50A Max? And the 2 x 100 is actually the AC Out 1 capacity? (all of which is when the grid is available obviously) Ingo Quote Link to comment Share on other sites More sharing options...

And the 2 x 100 is actually the AC Out 1 capacity? (all of which is when the grid is available obviously) The transfer switch is on the input of the Quattro. It is called a Quattro (Four in Italian) because it has two inputs and two outputs. The 2 x 100A indicates that each of the inputs has a 100A capacity. The second output has its own contactor that disconnects it if there is an outage (so you put your non-essential loads on that output). That contactor is only rated at 50A. There is no such contacter on AC-out-1, so it can handle the full 100A (if the grid is on of course). So you are mostly right... :-) Quote Link to comment Share on other sites More sharing options...
Ingo Posted September 8, 2018 Author Share Posted September 8, 2018 Thanks for the confirmation. I will make double sure not to overload AC-2 Out with anything more than 50A. Ingo Quote Link to comment Share on other sites More sharing options...

Same rule as for cabling, the breaker is there to protect the cable, or in this case the big contactor that has to switch on and off :-) Quote Link to comment Share on other sites More sharing options...
