what a mess ! (nightmare electrical situation at old house)

Ah well, it seems to be unavailable.

FYI 250 and 300 watt incandescent are now sold as 'Photo floods' and are still available

I have some three hundreds.

Talking about the flasher widget (not being available).

 

[RustyShackleford]

I don't think a toner widget will help identify the noodles.

Put a tone on the cable, then go see which neutral it's on ? (I already know which hot, having mapped the breakers). Or because the neutrals tend to be all jammed together in the gutter, difficult or impossible to tell which one is toning ?

 

[ptonsparky]

Surely everyone has a Time Delay Relay they can use to whip out a flasher in a few minutes.

And they are/were typically rated at 60w ma.

No, I don't have one, and . . .

I have a couple of them as well that I use for auxiliary heat to my greenhouse heater on really cold nights.

Back to OP (referencing points #2 and #3) ... what is the point of a MWBC, if you immediately (just inside the crawlspace from the outside load center) split it into two /2 cables ? To lessen the fill in the PVC nipple ? They didn't do it for all the MWBCs, but with several of them.

 

[ptonsparky]

Still one wire less.

 

[RustyShackleford]

Still one wire less.

For the 3ft or so from the load center to the j-box where they split it into two separate circuits (two /2 cables).

Yes, not worth it. J boxes and labor must have been low back them.

 

[tortuga]

Still one wire less.

In terms of de-rating its two conductors less. Not sure if it matters on a short nipple but I think you'd have to consider that if it were longer than 24"

 

[retirede]

Still one wire less.

Can be useful when the neutral buss doesn’t have enough points as was the case on some older panels.

Evidently j-boxes were expensive then too I say this, because this trick (splitting the MWBC into two /2 cables) was done twice on one j-box. One cheap plastic 18 cu-in j-box. That's right, there were fourteen 12awg wires, plus ground, in one of those little boxes.

 

[rambojoe]

Of course ther's always the goog 'ol super88 j-boxes...
Or worse, the harbor frieght tape i always seem to get for christmas, you know, the already dried out stuff?
