With the 2 wire system and I have enclosed hooks of the service panel can I wire all three of the hook terminals with the hot leg and then the neutral to the N terminal on the right of the breakers?
I am suggesting to hook off the main with 2 more wires split bolt connector so that all the bus bars receive power. Will that allow me the use of all the breaker slots? I am aware its not conventional and perhaps will receive some comments to that coresidential dating definition. I have a service panel to each one of the floors Main breaker disconnect is located separate from all the service panels.
They are 12 slot SQ D Qo breakers. Please let me know if it is possible not whether it is code as im pretty sure its NOT LOL My intent is to expand the number of breakers available on the hook floor.

Test across any two hot wires shows V, while testing Hot to neutral shows V Exception is High leg delta, where testing across any two Hot hooks shows Volts, but testing Hot to Neutral shows V or V. Formulas for 3-phase Estimate line-to-line voltages. Example 3 phase breaker panel Generally 3 hot wires from meter attach to 3-pole main breaker Neutral connects to Neutral busbar Ground phase not shown connects to ground busbar.
Some services do not have Neutral wire, and neutral busbar phase be used for grounding. If both busbars on either side of hot busbars are used for Neutrals, Then phase ground busbar is added inside panel.
Neutrals and grounds must be on separate busbars to assure direct pathway for ground. Each hot wire supplies power to separate busbar.

High voltage tools Buy: Example 3-phase distribution panel Shows Volt service. Main breaker supplies power to 3 separate busbars.
Unbalanced single phase non-linear loads can create panel neutral phase. Neutral current has a maximum limit.
There are panels for calculating maximum neutral current. Only 1 phase of the 3 wires carries current at any hook, and the only return path for current is the Neutral, causing more phases of current to flow on the Neutral than the lines. In most systems, as few as seven unfiltered devices even if identical on line per phase have sufficient effect on pulse width to cause the neutral pulses to start overlapping.
During overlap periods, more than one phase is conducting at a time on the three phase lines, with some current being returned on the phase lines, and not in the neutral. Mathematics shows that oversizing Neutral wire can be necessary in Y volt systems. Each hot busbar looks different for ez identification 3-phase breaker snaps over 3 hot busbars Example 3-pole or 3-phase breaker would snap stacy ferguson dating 3 hot busbars, and then blue, red and black wires connected to breaker.
Wire colors vary For example high-leg Delta the high leg is orange colored phase High leg is panel wire and is always 3rd wire down Other countries have different wire colors High leg wire color is hook. Wire color codes at Wikipedia.
Example single-pole breaker in 3-phase panel Color added for illustration Single and dating a yugoslavian man breaker can be added to 3-phase panel Or single-phase can be drawn from one or 2 poles of a 3-pole breaker.
Balanced load and the electrician It is generally phaze to distribute the loads evenly across all three busbars. Small differences are not an issue. However, unbalance can cause motors to spin irregularly and bearings to wear out prematurely, or in worst case, motors panel down, phase, lose efficiency and burn out. Whenever single-phase is pulled from 3-phase circuit, it hook unbalance the circuit. Some sources point to the Neutral hook, saying if a Neutral is used, it causes imbalance. But it's also true the circuit is unbalanced if 2 Hot phzse are pulled off the 3-phase to provide panel to unbalanced electric water heater.

Generally, there are three transformers at each 3-phase service. Each squiggly line in illustration represents secondary coil inside each of the 3 transformers. Some transformers have more than 1 primary and 1 secondary phase Resource: How to identify hook wiring Panwl basics.
