Is this a NEC violation?

[asaini]

I am designing a Pump control panel; and I have 208/120V power available near this site.
The loads are:
1, 2HP Pump (to be fed by 1Ph, 208V)
4, 1/2 HP Pumps (to be fed by 1Ph, 120V)
1, UPS for control power -750VA @ 120V
Control Panel Light, Blower, and an Outlet.

I’m planning to bring a 1PH, 208V feed and install a main CB-50A/2P in this panel, and distribute the power to all these loads via Distribution Blocks and then individual CBs.

Is using this method for distribution in the control panel a NEC violation?

Add up the loads. Does it exceed 50 amps if non-continuous or 80% of 50 amps if it is continuous? Regarding your distribution blocks and circuit breakers, you must comply with the NEC tap rules. Suggest hiring a licensed engineer or electrician.
