Please inspect my panel build

I need to finish wiring the receptacle and XLR, but see pic below.

Contactors are rated for 40a with a 24vac coil voltage.
Transformer is multi primary with 24vac secondary; 120vac line to the red power line.
Red power line is going into main power contactor and out to hot bus.
Black power line is going into main power contactor and out to SSR.
Neutral line is going to neutral bus.
Ground is going to ground on receptacle which is grounded to chassis on element enclosure.
SSR is going to element contactor (contactor out to receptacle; not wired yet).
Hot line bus to element contactor (contactor out to receptacle; not wired yet).
Secondary 24v line is going to switches with common to the contactors (not wired yet).

PID is an Inkbird ITC106VH has 3 inputs (pins 3-5) going to XLR panel mount, neutral (pin 12) to neutral bus, and the both the supply lines (pins 9-10) are going to the hot bus. Edit: looks like pin 10 would be neutral when using 120vac.

Why 24v contactors?

 

[nrjones89]

So that I can use any kind of switch, not just 120v rated switches. Having a transformer means I can run a 24v pump and add other stuff later.

A 24v AC pump?

A 24v AC pump?

No, a 24v DC pump. I would use a 24v DC motor. It would just need a rectifier circuit from the power supply. Cut an impeller out of a PSU case (SECC steel) add a brass/stainless bearing and build a case out of PVC with a gasket to seal the driveshaft.
