Mule - first of all, what are "kearneys"? And if I'm reading this, you worked them "hot"?

Main breaker at the pole? Never heard of such a thing. What POCO? At the pole, the only thing we might see is fuses - but they're not designed to protect the service drops, they generall protect the transformer and it's load.

My previous post said that I unloaded the meter and pulled it...so it would not be hot....

We have two Poco's here and this one is primarily rural. They supply a pole, meter loop, and the main breaker enclosure to the customer which is free. The customer only pays for the main breaker. This type of POLE installation facilitates wiring mulitple rural structures...hence the pole in the back yard.

No, another misuse of words.

The SCA, available fault current, was up there.
AIC is the rating/sizing of a protective device.


Thanks....:D This old timer, is part hillbilly....Never heard of SCA? standing current available? secondary current available? stupid current awaiting? wild guess I thought AIC was Available Inrush Current...NO?

I bet you knew what I was trying to say....

Maybe this "mule" will someday learn to be punctual......but I doubt it....

SCA = usally Short Circuit Amps, althought some call it Short Circuit, Available
AIC = Amps Interrupting Capacity

Right here.
Oops...thanks be sure and "keep an eye on me"...but Im sure you will
Think of AIC as the "heavy duty-ness" of the equipment, much like you can buy 250 volt and 600 volt rated disconnects.

Think of SCA as the actual fault current available.

It is heartwarming to see an appliance delivery guy who tried to sell a cord to a customer without any credentials to do so get a lesson in electrical theory(non lethal of course). I certainly dont want the little bugger to kill himself. I do want him to get a good enough whack to put the fear of God in him and go back to all of the rest of these appliance guys who take our jobs and let them know what happened to him. It is also good for the customer to see him on the floor doing the funky chicken for thinking of not using a licensed and insured electrician.

That's the reason those fuses are 200k,....didnt know they could pack that much current in there .....:D

Do disconects come in different ratings? I thought the smaller ones go where you dont have much space....

For those that like plumbing analogies.
SCA = amount of fault current available = Gallons of water that can come out of a broken pipe.
AIC = ability to cope with the amount of fault current = how big, in gallons, is the bucket below the broken pipe.

Sounds like a short to me.....:D mixing water and current

Thanks for the education...truely I always thought it was available inrush current
