Hot tub install codes

I'm getting a permit and having an ESA inspector coming so I want to do it as per code. Most electrical shops will tell you " you should be ok". I want a yes that's good

I know this is alot of questions, if I can't get an answer I will just suck it up and buy the ontario ESA code book. Hopefully some of you can shed a bit of light to my questions.

-When you drill the hole to pass your wiring through the house, what are the codes for drill through the floor joist that sits on the foundation. Distances from edges, load bearing walls etc

-What are the codes from drilling through floor joist inside the house to pass the 6 gauge wire, edge distances, load bearing walls.

Is there a code for distance between clamping the wire in the house, is plastic clamps acceptable?

Are dual breakers acceptable or should I do a pony panel as my panel is full? I need to put in a 60 amp breaker.

Is it ok to mount the gfci box on a pressure treated 4x4 post that is secure on the deck and not on the house?

Can I use liquid tight conduit from the house to the gfci box that would mounted on the deck?

Since the deck is not attached to the house and free floating. Do I need to put expansion joints to the PVC conduit that goes from the gfci to the ground?

Since the deck,gfci and hot tub is not Attached to the house and free floating, is it ok to go from pcv to liquid tight conduit at the hot tub end, considering that the liquid tight conduit would act as an expansion joint for Any movement.

Does ESA code require a bonding jumper rod from the hot tub to a spike rod in the ground? If so what is the depth. The rod needs to be pounded in the ground and were is the jumper installed on the tub itself? Or the ground bar were the other grounds are or do I wrap it around the pump or something metal that is bonded in the tub?

I know this is alot of questions, let me know if one of you can answer a few of them.

I suggest a good place to start is the book Electrical Code Simplified House Wiring Guide by PS Knight, I believe that it can be found at Home Depot for ~ $15 or so. It's what was recommended in order to study for the Electrical Endorsement portion of my Red Seal exams in Plumbing.

Ask the inspection agency or the inspector how he wants it done.

I know you will not like to hear this, but; Spas, hot tubs and pools are not DIY projects and should be installed by a professional.
Especially the electrical part!

Thanks so much for the replies.i bought the book. As far as getting it installed by pros I get what your saying. But I'm getting it checked by a certified electrician before putting power to the whole thing
