,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.

ground or the frame in any way.
The megger uses much higher voltages to check resistance than a normal Volt-ohm
meter.

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
