Question 1

Local 52 address

Answer 1

19-02 Steinway St

Astoria, NY 11105

Question 2

Power factor

Answer 2

When the voltage and current are out of phase they never peak at the same time. The efficiency of the delivery of power is reduced (i.e. - 0.7)

Ballasts can only use a percentage (70%) of the power it draws/has to draw a percentage (30%) more than it needs. The rest cycles back through the neutral (not good).

Watts/(V x pf) = A

–

In AC, the ratio of the actual or effective power in watts to the apparent power in volt-amperes, expressed as a percentage.

Inductive loads cause the current to lag behind the voltage, resulting in a power factor of less than 100%

Question 3

What size genny’s do we use?

Answer 3

1200-1600?

Usually 1400?

Question 4

What is a 407?

Answer 4

a term assholes will use for a baby (1k)

Question 5

Who is the vice president of 52?

Answer 5

John Fundus

Question 6

How many amps are used if you dim a 1,000w light to 50% ?

Answer 6

1,000w/120v = 8.3 amps 
120v/8.3a = 14 ohms (resistance)

I = E/R

60v/14R = 4.3a
60v x 4.3a = 258w

Question 7

Capacitive load

Answer 7

When the current leads the voltage

In a non-power-factor-corrected ballast the current rises and falls (typically a quarter cycle, 45 degrees) ahead of the volts and loses efficiency.

Electric ballasts/dimmers

Question 8

Power factor equation

Answer 8

Watts/(V x PF%) = Amps

Question 9

LED

Answer 9

Light Emitting Diode

A solid-state illumination engine

Question 10

How many pins in a socopex?

Answer 10

19

6 circuits

Question 11

3 things to keep in mind while running cable in public

Answer 11

• Tripping hazards (crossovers/mats)
• street crossings should be un-banded
• avoid the possibility of cars parking on it

(connector locations, avoid crossing water/sewer lids)

Question 12

HMI headers

Answer 12

12k/18k - 4 pin

6k/9k - 3 pin

2. 5/4k - 7 pin (notch between pins)
3. 2k/1.8k - 7 pin (notch “aligned” w/pin) & 575s and M8s

Question 13

Who is the business agent of local 52?

Answer 13

Ray Fortune

Question 14

What is the phone number of the local 52 office?

Answer 14

718-906-9440

Question 15

Inductive loads

Answer 15

cause the current to lag behind the voltage, resulting in a power factor of less than 100%

Question 16

Line loss

Answer 16

4/0 - 1.02
2/0 - 1.6
#2 - 3.25 volts

(per 100’ per 100 amps)

Question 17

Insulation rating of 4/0, 2/0, #2

Answer 17

90 degrees celsius

Question 18

“make first, break last” meaning

Answer 18

make ground connections first (neutral 2nd)

and break ground last (neutral 2nd to last)

Question 19

What is a GFCI?

Answer 19

Ground fault circuit interrupter

a special type of circuit protection required around water.
detects leakage current – current not returning to the power source that could pose a hazard
