A Picture is worth a thousand words

[acrwc10]

I was looking at a TI, yesterday and they need a new feeder to the unit. So when I look at the main disconnect to see what they have this is what I found. Along with a dozen other violations, this was my favorite. What do you think the rating of the "C" clamps are?

Nice.


Cooper-Bussmann sells a listed product for the same function.

Isn't that a violation of 310.4?

That's one way of curing a loose fuse holder.:grin:

I'll have to remember that.....

 

[acrwc10]

110.3
110.14 and then some.

I would say 200amps ea. So its good for the 400amp fuse

I said these were listed, but I think I was wrong.

 

[acrwc10]

I don't think I would have liked those either.

Do they say they can be installed hot?

 

[zbang]

At least it's not vice-grips.

What does the phase tape signify?

What does the phase tape signify?

You're thinking a fused neutral?

 

[Dennis Alwon]

Look at the color of the blades on Red & Blue phase- line side. Looks like the blue phase needs a clamp also.

Depends how tight they are done up.

Surely theres a table in the NEC for that...?

maybe they are patriotic, because this is a 240V 3phase. Come to think of it I have a rotation meter that has red, white, and blue leads, for phase conductors. What is funny, the red tape is on the bar on the left, and the red taped conductor is in the middle. I'll post the 2 other pictures, more violations. The neutrals have yellow tape on them, but I am going to give them the benefit of "maybe" it was white tape that turned yellow because of heat.

POCO standard here is red/white/blue for A/B/C phases.

POCO= we march to the beat of our own drum.

Here is another picture. Now there is the obvious double lugging, but check out the color of the Blade on the right. I need to I.R scan this box. (not that it would change the need to change this disco.)

This disconnect is very close to failure, the insulating block behind phase A has significant heat damage, both fuse holders of phase A and C are damaged, and the knife on phase C is damaged, all by heat, would be a great up sale. and the fact that you can't parallel 3/0 to feed a 400 amp disconnect or to the load, so there is definitely some problems, wonder what the load is in amps? looks like an old Wadsworth disco.

No, there isn't . . . and don't call me Shirley.

POCO standard here is red/white/blue for A/B/C phases.

How patriotic.
