Short answer is yes...but IMO you need to keep the same number of levels wired to each plug. So lets say you have a 10 level rack. You could put each level on its own plug. You could put two levels per plug for 5 plugs total or you could put 5 levels per plug for 2 plugs total. Also since you will only have one T-stat probe I like to use a different color cord on the set that has the T-stat probe on it. For me I use a green cord for the T-stat probe level then brown or white for the rest. This way I know if the green cord is not pluged in then you are no good. As long as the green plug is plugged in you should be good to go!
