I am new to this who Power calculation thing, what does the "L" stand
for in the notation "L6-30"??
Does it mean "Locking" or "Leviton" or something else.
And what does the "6" means as well? I asusme the "30" is Amps.
Any insight on this would be very helpful. I know this is an easy
question, but I need help.
Thanks all!

It's called a "NEMA" number, and it describes plugs, outlets, and cord
bodies, to make it easier to match things up

Locking, 250 volts, 30 amps
Take a look at
www.leviton.com/sections/techsupp/nema.htm (straight blade)
and

The information seems easy to find. I just did a search on "NEMA
receptacles".
An "L" at the beginning is used for a locking plug or receptacle.
The number before the dash indicates a row on a chart, representing
different voltages receptacles are designed for:
1- 120V no ground
2- 240V no ground
3- 277V no ground
4- 600V no ground
5- 120V
6- 240V
7- 277V
8- 480V
9- 600V
10- 120V/240V no ground
11- 240V delta no ground
12- 480V delta no ground
13- 600V delta no ground
14- 120V/240V
15- 240V delta
16- 480V delta
17- 600V delta
18- 120V wye no ground
19- 277V wye no ground
20- 347V wye no ground
21- 120V wye
22- 277V wye
23- 347V wye
24- 347V
The number after the "-" is current capacity in amps. Standard
capacities are 15, 20, 30, 50, 60.
There could be a final "P" for plug or "R" for receptacle.
A L6-30 is a locking plug or receptacle for 240V (ground but no
neutral) at 30A.
Hopefully, I got that right

The number additionally indicates the number of poles (current carrying
conductors), and wires (total including ground).

Not all connectors are made in all configurations. For instance:
Locking connectors are defined, but do not appear to be made in NEMA
configurations in the 50 and 60 amp sizes. Non-NEMA connectors
are in common use, as are Pin and Sleeve type connectors.
Straight blade connectors are not defined for voltages above 347V.
Locking connectors are not defined for L3 and L4 (277V, 600V).
Locking 15A connectors are not defined for more than 3 wires.
30A is the most universal size in locking connectors, available for
L5 thru L23.
Other special NEMA types:
ML-1 125V 15A 2-pole / 2-wire miniature
ML-2 125V 15A 2-pole / 3-wire grounding miniature
ML-3 125/250V 15A 3-pole / 3-wire miniature
FSL-1 28V DC 30A 2-pole / 3-wire grounding
FSL-2 120V 400HZ 30A 2-pole / 3-wire grounding
FSL-3 120V 3 phase delta 400HZ 30A 3-pole / 4-wire grounding
FSL-4 120/208V 3 phase wye 400HZ 30A 4-pole / 5-wire grounding

Don't forget "C" for connector body (cable end).

Not bad.. :-)
