Unbalanced final ring

[Pretty Mouth]

By chance this popped up on youtube earlier, it shows T+E overloaded to destruction. The experiment is a little flawed IMO, because he doesn't really allow enough time for the smaller overloads to reach their peak temperature, but it still may be of interest.

Popped up in mine as well, looks like the algorithm is finding us!

I have an old Pichill 180A stick arc welder that gets dragged out occasionally for some heavy duty welding. On a few occasions, when it's been out and I've been bored, I've connected the odd metre or two of T&E or singles between its clamps just to see what happens at various currents.
General conclusion is that it'll take considerably more current than you might think before damage occurs.

Why not rebalance the ring by extending it in one of the cavities? It's an old ideology but in theory works. Calculate the length to the two sockets feeding kettle and dryer, for example, by splitting the ring. Then calculate the distance from the other side of the split ring socket back to the CU. L1 = 10m and L2 = 15m, add a 5m figure of 8 onto L2 and reconnect the ring. 15m/15m each side of the ring to the heaviest loads

Diversity wipes out the above though. But something like this I would look to do at design stage and make it a none issue

Thx, but:
"L1 = 10m and L2 = 15m, add a 5m figure of 8 onto L2 and reconnect the ring. 15m/15m each side of the ring to the heaviest loads"

Did you mean L1 not L2?

I think he means Leg 1 and Leg 2.

Yep! Edit button was disabled by the time I seen it. Hopefully the 15m/15m clarified what I intended
