This is a picture of two sets of two circuit breakers for one of my 5-ton HVAC units. It's the top to breakers on the left and right that I'm referring to.

I'm assuming the unit is 230V, and the two top breakers are tandem, so my understanding is that it's a 230V 45amp load for the left condenser, and the same for the right Air Handler, but there is no plastic handle tie connector between the two of them. Does this appear to be true, and should I be picking up a handle tie like this one to tie them back together:
