Is my circuit overloaded?

Pictures attached. If needs be I will attempt to open up the terminal box to get an idea of the wiring in there

The wires could be for an internal thermal protective device or maybe even a dynamic brake. Maybe can you give the make and model number of the motor?

The plot thickens somewhat...
I tested the current draw and 1.8Kw+ motor only draws 500w when running. Could the loose wires have something to do with the low current draw?

was it under load when you tested it. it wont draw more amps if it doesnt need to.
the extra wires might be for a 2nd capacitor. sometimes there are 2 in parallel.

How did you test the current? What instrument did you use? 500W isn't a current measurement it's a power measurement so I'm a bit confused about what you measured and how.

Induction motors or squirrel cage motors are generally at their most efficient when they're under full load, if they're free wheeling (no load) they often draw around 25 or even 30% of their full load current even though they're just rotating free and doing no useful work. Likewise the power factor of a motor usually improves as the load increases.

There's no hard and fast formula for off-load current draw, it very much depends on the individual motor but single phase motors have higher inefficiencies. If the saw was not actually cutting anything when you tested it then the power consumption of 500 watts would be expected.
