I think I’m screwed with Tray cable

I have some Triy cable. It’s not rated direct buried. It will be in a conduit, but it’s not a raceway because it’s just too exposed ends that currently have UF wire in them.
I was gonna try and pull it through and claim it’s not a conduit run cause then I don’t have to worry about conduit fill since it’s just a chase

But then technically, I’d have to have a direct buried rated TC cable correct even though technically it’s not direct buried

It wouldn't need to be direct bury, but suitable for wet locations. Have you looked up the markings?

Does the conduit chase make it so it’s not direct buried I would assume to get past that classification it would have to be a complete raceway
The inspector I have we’ll find anything and call it out

It’s communication wire for 5p enphase battery to the controller

It’s rated wet location
I do not have the wire on hand the listing just says wet location

Class 2 or Class 3 comms I would not worry about it, I think your fine.

I tried to get that from the manufacturer straight from end phase and their tech-support couldn’t tell me -the cables listed to run with line voltage so at least that gets me by

Why didn't you run it in the raceway with the power conductors as recommended by Enphase?

Why not run a complete raceway?

I think it will be fine (other than less protected) if outside a raceway but the code rather oddly does not allow it.

No, if it is in a chase it is not direct buried and doesn't need to be rated as such. Think of it this way, what if it was in a 7 foot diameter tunnel where they wash down with hoses on occasion? Technically that is no different, just a bigger hole.

I am- I am using an existing conduit with if wires already pulled
 
Those 5p enphase look pretty interesting, I took a quick glance at their website and they have quite a few docs, but I did not find anything on the class of the circuit. I'd be currious if anyone knows is it class1 class 2 class 3? now in 2023 we have class 4..
so many classes.
They did have a brief on the cable they supply:
I personally like tray cable, the wire has a NEC type printed on it THHN-THWN-2 etc,
it think its outer jacket is more durable than NM even without the 'joist pull' rating.
HVAC people have been using it for ages to wire minisplits, though its slightly annoying when they use the type that does not come with a green wire..
 
I believe it's Class 2, maybe Class 3, but it's wired like Class 1 so it complies with the NEC. It's CAN bus comms. The newer battery system (10C) also has 24VDC power so that's probably Class 2 or maybe even actual Class 1.
 
Thanks I ended up hitting a snag so I had to trench a different way so now it’s just everything‘s all in one conduit by itself with nothing else

On another note for your Solar guys, my power companies complaining that my 200 amp service disconnect outside does not meet their lockable definition. Anyone have any issues with that

What kind of disconnect is it? What are their rules. These things are quite local.
 
This is what they sent when asked

Grid:



“7)Standards: Customer-generator shall furnish, install, operate and maintain in good order and repair, all without cost to CLPUD, all equipment required for the safe operation of the net metering facility operating in parallel with CLPUD’s electrical supply system. This shall include, but not be limited to, equipment necessary to (1) establish and maintain automatic synchronism with CLPUD’s electric supply system and (2) automatically disconnect the net metering facility from CLPUD’s electrical supply system in the event of overload or outage on CLPUD’s electrical supply system. The net metering facility shall be designed to operate within allowable operating standards for CLPUD’s electrical supply system. The net metering facility shall not cause any adverse effects upon the quality or reliability of service provided to CLPUD’s other customers. The installation shall comply with the latest revision of IEEE 1547 as well as all applicable regulations of the National Electric Code and the Oregon State Building Code. Inverters used in net metering facilities shall be certified to the latest edition of Underwriters Laboratories (UL) 1741”

I don’t see why my service disconnect won’t work—-

That's all basically inverter listing and grid configuration standards and zilch to do with a disconnect.

I see no issue.

I mean, around here (PG&E) they use to require a disconnect for the solar, which had nothing to do with the service disconnect. Around here, they dropped that requirement years ago for single phase self-contained meters (CL320 or less).

I hear it's still typical most places for a utility to require a bladed lockable disconnect for the PV system (and battery system, if one disco can't do both), but that's not the service equipment nor specified in the info you quoted.

I've never heard of a utility having restrictions on what kind of service equipment you can interconnect to on the load side, if it's otherwise acceptable service equipment to them.

Sounds like you've run into someone green who is spouting BS. Maybe he needs to pay more attention to his webinars so he can figure out which doc he's actually supposed to send you. 🙄😆
