The cables and plugs used in hot tubs are J and J which are the grey moulded plugs which connect onto the side of the spa pack and AMP which are the opaque 4 pin plugs connecting directly to the circuit board.
Hot tub pump capacitors to fit every style of pump.
To identify the capacitor you need, look for the microfarrad rating on the capacitor. It will be a number like 14 16 30 35. This is the only number you need. You should also check the dimensions of your cap and make comparisons with the ones shown below.
ALL of these capacitors are made to fit Italian EMG motors, the style of motor that has "ribs" on the side and a black plastic capacitor box on the top. They will also fit many other brands.
Correctly sized capacitors are very important if your pump is to retain it's EU IP55 regulations of splash-proofness. The capacitor MUST be positioned inside the capacitor box located externally to the motor body. This box will have screws and a seal to prevent the ingress of water.
