Best option for spa wiring

Folks,

I've done a number of wiring jobs where everything was indoors and I only had to deal with romex.

But running a circuit for a hot tub is throwing me for a bit of a loop. My investigation shows that I can't run romex inside liquid-tite, but I certainly can run that indoors.

How would I best go about running this circuit? Do I get enough 6/3 romex and then strip off the outer insulation to run inside liquid-tite? Or do I setup a waterproof junction box outside where I change from romex to THHN?

Sorry if this seems like a basic question, but installing a subpanel in my garage seemed to be a hell of a lot more straighforward than this project, and there's a ton of conflicting info out on Al Gore's internet.

Thanks in advance for any advice,
Rick

Chris,

Appreciate the link. I'll read through code 680, and check with my local inspector to see if I need to do anything special to comply here.

I did one for my son with 3/4" PVC conduit. The last few feet of flex was connected to the end via a terminal adapter and liquid-tite fitting. The inspector was happy with it all.

I used #6 but if your load doesn't exceed 50 Amps you should be able to use #8 THHN/THWN with #10 ground. If you have a large 240 Volt heater (meaning low neutral load) you might be able to use #10 for the neutral. Compare that with Romex (NM) where you need #6 for 50 Amps.

We sleeve the last few feet of romex all the time and although a violation (wet area) never EVER get called on it.

To be compliant, change to thwn at a JB. This puts extra splices in the circuit and because I do a ton of troubleshooting, I'm not a big fan of extra splices.

So does that make it right? I speed once and awhile, it's still against the law...

You need a disconnect anyways... do the job right, or don't do it at all...

What's your point? Did I imply otherwise?

Then.....drive the speed limit or don't drive at all.



Don't start with me dude.:mad:

You choose when you can safely break the law and I choose whe I can safely violate the code. Same thing.

I always say, follow your conscience--not the laws, rules, or codes.

Here's some laws that are still on the books in some states. There's a million more where these came from:


It is illegal for a driver to be blindfolded while operating a vehicle.


Dominoes may not be played on Sunday.

You may not drive barefooted.


It is illegal to maim oneself to escape jury duty.


It is illegal to impersonate a person of the clergy.


Women are able to retain all property they owned prior to marriage in the case of divorce. However, this provision does not apply to men.


Masks may not be worn in public.


Putting salt on a railraod track may be punishable by death.


Boogers may not be flicked into the wind.


Bear wrestling matches are prohibited.


It is legal to drive the wrong way down a one-way street if you have a lantern attached to the front of your automobile.


Men may not spit in front of the opposite sex.


Incestuous marriages are legal.


It is illegal to wear a fake moustache that causes laughter in church.


You must have windshield wipers on your car.


You may not have an ice cream cone in your back pocket at any time.

My point is, do you think it is the smartest thing to give bad advice on a DIY forum, especially since you know better? :mad:

He might as well go to Home Depot and ask them...

A) I didn't tell him what to do, only told him what I do.

2) If it WAS advice, it's not bad advice. There is nothing mechanically wrong with it. It is a technical violation.

I know more about this stuff than you and all the Home Depot guys put together so you are going to have to find another way to try and insult me..

I'm not about to have a argument with someone who justifies doing non code complaint work...

Oh boy. Here we go AGAIN.
You may not be a fan of splices, but the rest of us here are not fans of NON-compliant work.
This is not advice. I'm just saying how I would do it. :p



You know what, make your splices bulletproof then. Or better yet, DON'T make splices. Do it the right way and run the NM to the disconnect (if it is mounted on the house) and go from there with THWN in conduit and the maximum allowable 6' of sealtite at the tub.

Read the post. Did I stutter?

That's exactly what I would do but the last few feet of the run, out of the attic, down to the disco, sleeved in NM, would be non compliant. THEN I suggested changing to thwn to remain compliant. If I somehow suggested running the NMout of the building straight to the spa, my bad. I assumed from the original post that he knew that a disco was required and was inquiring about a method to change wire types.


the maximum allowable 6' of sealtite at the tub.


Got a code reference for that one? You can run as much sealtite as you want because OBVIOUSLY you would put a GC in it....unless you were and idiot.


We all know that the wire in NM is thhn but since it's not marked, it's a technical violation. Sue me.

Also, MC is not marked on the wire but don't you ever run it in emt, exposed down to a switch for example? What ever.

Who elected you to be the head Dbag?

Look...if this was a pro hangout, I wouldn't see anything wrong airing dirty laundry and shortcuts you take that you believe are fine. This is primarily a DIY'er help site. Therefore, it behooves us to ONLY give code approved responses. If you want to give some advice that isn't up to code, give it in private. If you do post it, make sure you indicate the right way, or that this is not the approved way to perform that task.

Name calling is pretty childish, too.
