My X and Y axis motors each have exposed wiring. That is to say, there is no insulation around the wires coming out of the motor chassis. This appears to be an electrical hazard as I will be operating with a water table.
It’s low voltage and amperage DC, no safety worries. Likelihood of water hitting it just right to cause a short is very small.

I agree with @Bill_A , the jacket around the wiring is primarily for abrasion resistance, not water protection. The insulation on the individual wires does that. You could put a spiral wrap around the wire bundle fairly easily and apply it selectively where abrasion might be a risk.

It’s been fine for years on hundreds of tables. If it bothers you, put some silicone sealant on them.
