Is it ok to run rigid or flexible metal conduit right up and into the spa service panel as long as i use a bonding wire to the conduit and spa service panel bonding bar?

My rigid metal conduit is within about 4 feet of the tub and I know code is at least 5ft or it has to be bonded to the tub so I assume that it will be ok to run the metal conduit the rest of the way into the tub as long as I use a bonding clamp on it and attach it to the bonding bar of the spa service panel

Thanks for your help

Yes. You can extend the ridged conduit with flexible conduit to the spa control box. You need to use the correct connectors. Your ground wire will run from your panel through the conduit and flex and land on the ground terminal in the control box. It must be GFCI protected.

Thanks for the reply. Also, as far as the flexible conduit does it have to be a liquidtight conduit or can it just be a flexible metal conduit?

Make sure it is an insulated ground in the conduit to the hot tub too

I don't have a code book in front of me, but I would install liquid tight. Even if it is not required (and I believe it is) it is good practice.

Liquid tight from what i saw is not cheap either...is it possilbe to buy that by the foot from one of the box stores?

You can use either. Liquidtight is expensive and I have not noticed any at the HD or Lowes. The connectors cost more than the liquidtight itself. As long as you have a ground wire originating in the panel you are good to go.

I have seen carflex at the box stores. It's all plastic with no metal wrap. It's real cheap and so are the connectors. It would work well in this application as long as you have a ground wire.
