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

21
Q

installing Cables through wood & metal framing member

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

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)

23
Q

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

24
Q

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

25
Residential boxes 1/2 (for siding) Mud ring (wall board)
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
27
bracket to support box (ceiling)
28
Residential box (steel stud) flagges use (sheet metal screw) to lock around steel stud
29
Residential accessories extension ring if box if set too deep in wall
30
Ganged boxes 12-3010 - need support for ganged sectional boxes
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
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)
33
Combustible - Loomex - Residential non - combustible - BX - Commercial
34
Two wire (neutral has raised edge) - no ground extra low voltage 0 -30 volts low voltage 31 - 750 volts higher voltage 750 to higher volts 30.5 - (doesn't exist)
35
Control circuit doorbell, garage button, thermostat -shield (cover PVC) - communication shield (from mutual induction or ghost)
36
Jacket colours Yellow GFCI Blue AFCI 40 - 50 feet
37
TECK has inner & out jacket (always copper) ACWU cable (almost always aluminum) - copper - not similar (apparently) weight difference?
38
Neutral supported cable (NS) - landline? Powerline? = attach to hydro in front of house neutral - grounded - 3 wire circuit #8 - 4/0 (AWG size) Triplex Duplex (one lives, one neutral) -copper (near ocean) -usually aluminum
39
Aluminum sheath cable (ASC) -aluminum & PVC jacket - like Pyrotenax (not mineral insulation)
40
Voltage rating (most rated up to 600 V) dielectric strength (measure in volts per mil (thickness) Temperature rating (melts plastic) UV Chemical environment mechanical damage
40
Cabtire - flexible cable flat conductor cable (FCC) - like flat loomex -called under carpet (offices)
40
Rubber (natural & silicone) flexible - extension cords & welding cable 55 degrees celsius minimum
40
Busbar (bare copper) -panels
41
Polyethylene -marked XLPE or X Link (cross linked) -thermosetting?
41
Thermoplastics (PVC) Polyvinylchloride (600 V limitation) T (dry) TW (wet and dry) TWU (underground)
41
larger cables (colour strip) common (neutral) conductors (white & grey) (green) (bonding) (grounding) (Bare) Anything other colour (live) (hot)
42
Joist & Stud Joist - horizontal (wood) Stud - vertical (wood and metal)
