Battery Cable Run
I have just had a Tesla Powerwall installed. Overall happy, but disappointed with the cable/pipe run around the electric box. They said it had to go in the bottom for MSC regs, going in at the top could cause leaks, which I can understand.
Could it have been done better? Any examples of something better?

Perhaps they could have used white trunking, which would be more consistent with the white powerwall enclosure and meter box, you wouldn't see the black cables snaking around.

... and possibly artificially extended the trunking so it is symmetrical in relation to the boxes.
Fundamentally they are right that the cable entries should be at the bottom. So the only improvement is aesthetic 'disguise'.

We said black because all the other trunking for HP and Air Con is black.

For the flexible conduit in the photo I don't think the colour makes a huge difference, the eye is drawn to the wavy/snakey conduit next to the two rectangular enclosures. But if I was having straight/angular trunking which wrapped around between the enclosures, then personally I'd go for white because I think it would blend in better.
But aesthetics are to everyone's particular taste.

A bottom entry to the meter enclosure also has its drawbacks.
Any water, insects and debris which get inside the enclosure over the years will end up in the bottom loop of the flexible conduit.
Personally I'd have done a side-entry in this situation.
The conduit should be nylon or polypropylene. Polyethylene rarely has adequate UV-resistant chemical added to it, and therefore degrades in sunlight over time.

@trebor12345 two cents worth from me. I can understand the reasoning for bringing the cables into the bottom of the enclosure but I don’t think that necessarily explains why the finished cable run has to look like that.
Looking at the photo, it’s the large exposed loop around the enclosure that makes the installation look untidy, particularly when the Powerwall itself is such a clean-looking bit of kit. Surely the cables could have been routed much more neatly down the side of the enclosure and then swept underneath with a tighter, properly supported radius, while still maintaining bottom entry and the required bend radius?
Just my take.

How can I tell if its nylon or polypropylene

Just my take.
Are you thinking the 3 pipes laying flat against the wall and side by side (rather than a bundle)?

Well I usually do it by feel, which is a slight problem here on the Forum.
@editor do you have a Tactile Plug-in we could implement?
However, in practice polypropylene and nylon tend to be manufactured with a thicker wall section, and will be completely opaque,
whereas polyethylene is the cheaper stuff being offered on Amazon and Ebay.
Since I doubt that you're considering replacing what's already there, you could just wait until the winter and see if it's disintegrating.
