...Coachman, are you using a 50 amp.GFCI breaker at the panel,or the new Square "D" Type 3R Hot Tub/Spa Load Center with the GFCI,and pull-out disconnect self contained..?? I use them and they're great..It keeps the disconnect outdoors for emergency disconnecting..You'd still need a 50a. breaker at the panel,tho'...Don't forget to bond the motor(s) to the control panel ground bar,with a piece of #8 solid THHN..
Good Luck on your 1st of many more to come!!
P.S....Many "Jacuzzi's" have a 1" K.O. in the control box..so,if you come in with 3/4" pipe,or liquid-tite,("seal-tite")..you'll need a set of reducing washers..
