I have had 4 hot tubs over the years and can't figure this one out at all! I have a older model G ,wires it has, a big blue,little blue,big red,little red white,green,no mater how I hook it up it will not come on,also in the past I used one 50 GFI 230 BREAKER,they told me to never use separate breakers on 230,info I found shows two breakers only one ground fault,please if anyone knows anything about it please please let me know! Thank youso much
