If you are referring to a megohm meter, it is a test of the Know what a Megger is and what it does
insulation properties of such things as electric wiring, motor
windings and high power antenna mounts. 636 Pg. 13
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
(1) A parallel connection. (2) A resistive element placed across Shunt Overloads
the terminals of an armature to bypass a portion of the current.
(3) A flexible electrical conductor designed to conduct 425 All Pages
current around the mechanical joint between two conductors.
(4) The resistive element (Usually of very low resistance) used
in parallel with a DC ammeter movement to bypass a
calibrated portion of the total circuit current.
Bad Ground You are using a Temp Run Box and you get shocked! Why!

The bridle hitch can consist of two,three, or four single hitches Bridal Hitch
(fig. 3-22), used together to form a bridle hitch for hoisting an
object 128 Pg 17
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.

Note: We do not use wire smaller than #20 in travelling cables Pulling Spare Wires (Example) 10% of 52
Wires and #24 outside travelers.
Largest wires are feeders to Hoist /Pump motor 515 Pg.26
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
The correct lube must be used on chains. The freight door motor is spinning but the door wont move, Why?
