Electricans came this morning to run wire for tub. 50 amp non GFI in the box to a 50 amp GFI on another box on the wall. Then about 20 feet of waterproof flexible conduit (sealtite) from the outside box along the side of the house to the tub area.
Is this amount of flexible conduit allowable by code?
-
It is my understanding, as a non electrician, that it is not. When I did mine, I believe the limit was 6' or so, and that included the couple feet inside the spa cabinet.
However, the rules may be applied differently in certain areas, so if you are concerned, try asking the electrical inspection authority in your city, county, township, etc.

As I read my 1996 NEC, 6' limit on non-motorized equipment (such as lighting "whips"), 3' max on motorized stuff (like spas?).
I used to be in the HVAC biz, we would be allowed to run longer than 3' sealtite to the outside condensers from the disconnects, so maybe there is an exception for spas?
At the advice of others here, I plan on running non-metallic rigid conduit up to the point where it enters the spa skirt, then go sealtite.
Of course what matters is what your local inspectors go by.

I'm considering running PVC conduit along the wall where the sealtite is clamped now, and just run the sealtight inside it. I don't see how this would be any different than wires in the conduit, and I really don't want to try and pull the wires out.
This is assuming I can't get the electrican to fix it.
-
This is a lazy electricians type of work. Don't let the inspector pass his work, he can't charge you to modify his screw up. Sealtite looks like crap on a straight run. The PVC conduit will look better and sags less over time. If it's not saging now, it will.
Good luck

I ran sc80 pvc conduit to about 18" from the spa, then switched to sealtite for the remainder. If I recall, I had to limit the length to 6' for the whip.
Keep in mind where the conduit runs, and if it would be considered subject to physical damage or not, thereby needing sch 80 vs sch 40. There wasn't much cost difference so I went with the 80 just to overkill.
But again, it's what your local inspector says that's important.

My electrician ran "liquidtite" same as "sealtite" from my outside box trenched down 18" followed the concrete patio (it's all curved) to the tub, roughly 40 feet.
-
Are you sure it's not a product called Tek-Cable? This stuff resembles sealtite, but it is wire bundled in sheath, bundled in metal conduit, then bundled in a Sealtite coating. It is very industrial, seems to be used a lot for wiring up Saunas and Tubs around my area.
-
No the actual cables are fished through the liquidtite, I know the stuff you are speaking of though.
-
After seeing what they had to go through to get the wire into the sealtite, it's not coming out. The sealtite is 7/8" OD, so I'm going to check and see what size PVC conduit is needed for it to go inside. I'll try to get the electrican to do it, but if he won't, I'll go ahead myself.
Nobody seems to work on your house as if it were their house.
-
Another thing you should be aware of is that there are NEC requirements on wire size and conduit sizes. I'm sure someone will correct me on this, but you cannot displace more that 75% of conduit area.
-
There are conuit fill guidelines, and they're really not that easy to interpret, at least I didn't think so.
I used 3/4" pvc to run my spa wiring. I had 2 #6 hot leads and a #8 insulated ground in the 3/4". I believe I could have ran a neutral in the conduit as well, and still be within fill limits. The inpector passed it, and he was extremely thorough.

Well, I talked to the electrican again and he says it's to code. But is looks like poo. I'm going to spend $20 bucks on some PVC conduit and run the sealtite inside it along the wall, because my patio now looks like a factory.
-
$6.13 on 1" PVC and a few hangers, ran the sealtite inside and it looks MUCH better.
Hey I'm a full member!
Tub arrives maybe Friday!

Good job!

I ran about 12 feet of 1" sealtight from the breaker box that is mounted on the house to the tub. No problem with inspection.
