If you are referring to a megohm meter, it is a test of the insulation properties of such
things as electric wiring, motor windings and high power antenna mounts.

We use a "megger" or "meg out" electrical wiring and equipment to see if it is shorted to
ground or the frame in any way.

The megger uses much higher voltages to check resistance than a normal Volt-ohm
meter.

Minimum resistance is 1 Meg Ohm - ANSWER Know what a Megger is and what it does

,The bridle hitch can consist of two,three, or four single hitches (fig. 3-22), used together
to form a bridle hitch for hoisting an object
A sling with two legs used to lift a 1,000 pound object will have 500 pounds of the load
on each leg when the sling angle is 90 degrees. The load stress on each leg increases
as the angle decreases; and if the sling angle was 30 degrees lifting the same 1,000
pound object, the load will be 1,000 pounds on each leg. Try to keep all sling angles
greater than 45 degrees; sling angles approaching 30 degrees are considered
extremely hazardous and must be avoided at all cost. - ANSWER Bridal Hitch

Note: We do not use wire smaller than #20 in travelling cables and #24 outside
travelers.
Largest wires are feeders to Hoist /Pump motor
We always have 10 % spares
10% of 52 = 5.2
On a calculator Multiply the percent 10 by the number you have and ÷ by 100
10 X 52 ÷ 100 = 5.2 - ANSWER Pulling Spare Wires (Example) 10% of 52 Wires

Notes:(Pi) π is 3.1416 and 231 Cubic inches to the Gallon
Area:
Remember to ÷ 6" ÷ 2 = 3 to get Radius
Area = π∙ r²
Area = 3.1416 x 3 x 3 = 28.27 inches or 3.146 x 9 = 28.27
Volume
Multiple are times height to solve for Volume
V = A∙H
V = 28.27 x 300 (25" feet x 12" = 300)
V = 8481 Cubic Inches
Since we already know there are 231 cubic inches to the gallon
8481 ÷ 231 = 36.71 Gallons - ANSWER PSI Formula and Gallons (Example) How much
oil to move a 6" jack 25'
