ga.sparky56,
you've a sore topic for me here,as i've gone toe to toe with a few excavators, architects and home owners on this.
( I refuse to service them unless i wire them MY way..)
For the most part, you'll note the larger municipal systems have external controls and disco's, however the common residential 2 float system ( and one alarm float) apparently has not subscribed to this techology as yet....
They come with the motor, long S cord ending in a molded male cord cap, which is then supposivley to plug into the ball float "feed thru" cord cap, assuming a 2" snag of cord caps that will rarely fit inside a bubble cover.
Even if you are lucky enough to do this, the methane with rot practically any al box on the market, not to mention any connections, buble cover nonwithstanding.....
The code? 430.102 ( note the 02' crackdown)
The manufacturer assumes the male cord cap & receptacle INSIDE the effluent container to be the motor disco.......it simply is a poor design, take it from a sparky who has navigated enough septic systems here.
The fix?
Use a Carlon # E970CE round box w/ 4 3/4" openings, get yourself 3--Carlon H978E strain relief connectors and pipe 3/4" pvc directly out the tank to an FS box.
There is usually a vent close by to secure a 2x6 PT pedstal to.
Make all the cords ( motor, ball, alarm) into the E970CE, strip the cords at that point and push them all up into the FS box.
( dux seal the 3/4" shut @ the FS box for extra credit.....)
There are then NO terminations within the tank to go bad, or IMHO, to need check on.
I then apply a Carlon E98TSC switch cover that is lockable to the FS box & feed all back to the dwelling.
