The electrical wiring outlet on most sumps of this type is below ground. There needs to be a conduit of some kind from the sump to the controller box to draw the cables through. If the sump was in the driveway of a parkade for example you need a conduit. When the sump is classified as a hazardous area the conduit has to be sealed saying bye bye to all 7 cables if one float needs to be changed. Might as well throw out both pumps and all the other floats too because you can't splice thier cables.
In order to avoid this I am questioning whether it is legal to end the conduit before the controller and use individual cabtire connectors for each float or motor where the wires enter the controller which would be above the hazardous layer.
