Wow, nice! On the first one which is the one we had, what is the small knob/dial for? Ours had the timer on left, oven control on right, but not the small knob. Interesting wiring on the second, would that be a 3 phase unit? | ||

TD Ovens On the older SS oven the small radio type dial is a infinite switch to adjust the intensity of the broiler while broiling.
The 2nd TD double oven is the great Micro-Thermal top oven model CMT-21, the power cable is a standard single phase 120-240 hook-up just like ALL US ovens and electric clothes dryers, How many homes would have 3 phase power to operate an oven any way ? | ||

Combo, the Miami house was 3 phase, built in 55? It needed different models of A/C which was not easy to find after the Fridig water cooled unit died in the late 80's. Most of the houses I've owned were 3 connector with NO ground as opposed to the newer 3 connector with ground. | ||

3-Wire vs 4-Wire
Cuffs, what you are describing (and what is shown on this oven) is a 3 wire split-phase system. You have two hot wires and a neutral, both the hots are ~120v to the neutral but they are ~240v between one another since the AC waveform is 180 degrees opposed. This is single phase distribution since the opposite hots are derived from a centertapped secondary on a single phase fed transformer. I have never seen a residential home with 3-phase power, but I suppose there could be one somewhere.
Recently they added a 4th wire to the standard 240v AC connection in homes. The 4th wire provides a true ground that doesn't carry any load current. In the 3 wire system the neutral acted as a surrogate ground. In the majority of residential cases the neutral and the ground are bonded in the service panel, so the neutral should be ground potential, but a 4th wire makes for an added safety ground. | ||

Here are the pics on the second Thermador I posted, before they are taken off Craig's and this wire discussion will be left hanging... | ||
