⩥ 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
636 Pg. 13
⩥ (1) A parallel connection. (2) A resistive element placed across the
terminals of an armature to bypass a portion of the current. (3) A flexible
electrical conductor designed to conduct 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.. Answer: Shunt

⩥ Bad Ground. Answer: You are using a Temp Run Box and you get
shocked! Why!

⩥ 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

⩥ Scaffolding should be tied to the structure using
#9 wire or tie-in devices. The first vertical tie
should be at the maximum height of 4 times the
narrowest base dimension. Additional ties are not
to exceed 26' vertically. Maximum horizontal
distance between ties is not to exceed 30'.. Answer: Scaffolding, You
have 32' of rise, you are using 3x5 scaffolding. Where will the tie off
points be ?
140 PG. 287-288
⩥ Counterweights (Typically) are hung to counter balance the weight of
the car PLUS 40% of Capacity Load.. Answer: How much should
Counterweight way?
240 Pg. 14
, ⩥ 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
515 Pg.26
⩥ The correct lube must be used on chains.. Answer: The freight door
motor is spinning but the door wont move, Why?
