Will the lugs in this switch allow for 2 4/0 conductors for (2) 200 amp panels?
EJ H. 
from Ohio 
December 13, 2016
Answer
The switch does not have dual lugs, and according to Generac they can be changed by the electrician installing the switch as long as the lugs are UL Approved. These would have to be found at a local electrical supply.

My installer is asking if this unit has a breaker? Will mate this transfer switch to a Model 6721 16KW Generac. Thank you.
Rob Smyth

Answer
The transfer switch has a disconnect only and is not a breaker. This is considered a pass through switch which means the utility power passed through the switch and the generator itself has the main line circuit breaker.
