Q

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

A
21
Q

installing Cables through wood & metal framing member

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

A
22
Q

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)

A
25
Q

Residential boxes

1/2 (for siding)

Mud ring (wall board)

A
26
Q

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)

A
31
Q

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

A
32
Q

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)
