Cable cutters (soft non-ferrous material) (BX)

Question 19

adjust potentiometer - electronics - insulated & metal side

Question 20

Install Armoured Cable

must be laid on face of masonry walls (buried in plastic)

if conductors are not larger than No. 10 AWG (used for extension of existing outlets)

CMA up, AWG down, then Resistance down

Question 21

installing Cables through wood & metal framing member

watch out for flat installations (studs)
-require mechanical protection

Question 22

Electrical boxes

identify boxes (for purpose)

start & end (box)
join middle (box)
approved cover (completely enclosed)
knockout holes (must be filled)
accessible (boxes) (attic, floor) (has to be accessible)

Question 23

Combustible combustion (wood frame) (not cement)
-Loomex NMD-90

Question 24

Residential boxes (metal) - up to 12 gang boxes typical
-can add gang
-need 6 inches of free insulated conductors

Question 25

Residential boxes

1/2 (for siding)

Mud ring (wall board)

Question 26

Residential boxes Plastic

some have gasket (vapour barrier) (moisture) - can’t get through

banana (yellow)

plastic - hammered
metal - screwed

Rule 12-300 - nail box to stud
4 11/16 or (over 4 inches) - need second piece of wood to support (any two sides) (need both)

• pulling plug breaks wall bits

Question 27

bracket to support box (ceiling)

Question 28

Residential box (steel stud)

flagges use (sheet metal screw) to lock around steel stud

Question 29

Residential accessories

extension ring if box if set too deep in wall

Question 30

Ganged boxes

12-3010 - need support for ganged sectional boxes

Question 31

Wet locations

normally use PVC boxes
RAB boxes (might be aluminum with gas garb)

Specialty boxes (floor box)

-Mounted before cements is poured (masonry box)
-need steel barrier to avoid keeping different circuits together

Question 32

Box fill

too many conductors jammed in box (possible cut conductors)
more conductors more heat

add one (duplex) - have to add or remove to conductors
-count number of wires (conductors)

-don’t count ground but wires
-one don’t count
-two or more (add or deduct) (conductors)

Question 33
