I saw LCL on a panel schedule on a set of plans and was wondering if anyone knew what it means. First time I have seen it. I think it might mean long continuous load but cannot find a definition for that either.
Anyone have an idea?

Thanks
 
to me sounds like a combination filter. R is resistor, L is inductor (reactor) and C is capacitor. These filters have a lot of applications: Harmonic reduction and isolation, di/dt protection, etc etc.
I may be completely off though; there could be a simpler explanation.

Typically LCL means, first that it is a continuous load, but also that the extra 25% is included... so it doesn't get duplicated when doing feeder calcs.

That was along the same lines as what I thought, wanted to see if someone else has the same thought.
Thanks everyone for your input.

I know that Westinghouse/Eaton Electrical/C-H has an "current limiting "LCL" breaker available as does SqD. As such consider the LCL as refering to a current limiting breaker.

The Eaton LCL breaker has an electronic trip with 200kaic@480v up to a 400at.
The SqD LCL is a CL breaker with 65kaic@480v up to a 600at.

So it may be best to go back to the specifier to get this defined rather than continuing to guess as to what LCL means.
