Learned a few things the hard way on this hot tub.

First off, since the hot tub was far away from the main panel, and there was a basement where more work would take place, so i ran a 90 amp sub panel, in SER.
Then found out, that to do that you have to pull a permit for the sub, then another after the sub is inspected pull another permit for the hot tub, or else the wire has to be in conduit. How or why that makes any sense, i dunno.

Now, i fail the same job, for not having seperate neutrals and grounds in the disconnect.
I've done a fair amount of hot tubs, i'm by no means a pool guy, but i do a few a year. I always buy the disconnects at the supply house meant for a hot tub (cutler ch) and hook them all up the same way (at least i think i do).
There is only one ground/neutral bar in this disconnect, i just checked. And never do i ever remember adding one.

Did i perhaps get a disconnect missing a second bar? Did something change in the code?
Maybe i've been doing it wrong all this time and getting away with it?

thanks,
Joe
