Construction preparation:

1. material asks:

Switch, electrical outlet: Norms model must accord with design requirement, have product certificate of approval.

Plastic (stage) board: Should have enough strength. Plastic (stage) board should level off, become warped without the turn be out of shape phenomenon, have product certificate of approval.

Other material: The metal expands bolt, plastic bilge brick of screw of wood of canal, galvanization, galvanization machine screw, wood.

2. main machines and tools:

Feet of red pencil, tape measure, level, line dropping, electric insulation glove, kit bag, ladder.

Hand hammer, cold chisel, pare hammer of line clamp, pointed mouth clamp, Za Zhui, tap, bushing, electric drill, report, broach, nail gun.

3. work requirement:

All sorts of pipeline, box has laid end. Level off of box binding off.

The lead of circuit already was worn, already finished insulation telemetering.

The oar work of metope, paint inside decorate the job to already all was finished.

2. clears:

With cold chisel the gently ash the remaining inside the box piece get rid of is dropped, at the same time other sundry along with all the others Qing Dynasty gives a case outside, using wet cloth rub-up of the dirt inside the box.

3. tie line:

Switch tie line:

ａ . The switch of same place cuts off the position to should agree, cut an operation agile, contact contact is reliable.

ｂ . The look line of electric equipment, lamps and lanterns should via switch control.

ｃ . Much couplet switch does not allow arch head link, should use total head of crimp of LC crimp cap to undertake branch joins again.

Socket wiring:

ａ . Single-phase two aperture electrical outlet has horizontal outfit and vertical stroke to install two kinds. When horizontal outfit, those who face socket is extremely right receive look line, extremely left receive neuter line; When perpendicular outfit, those who face socket on extremely receive look line, below extremely receive neuter line.

ｂ , odd. 3 aperture and three-phase signal of line of tie of 4 empty electrical outlet, 3-1.2 seeing a picture and attention of ground wire of graph 3-1.3 protection are received in upper part.

ｃ . Hand in, installation is in the electrical outlet of dc or different voltage when same place, due and clear distinction, and its outlet and electrical outlet form a complete set, all cannot substitute each other.

ｄ . Box is opposite socket many electrical outlet when lead joins, do not allow arch head link, after should using total head of crimp of LC crimp cap, have branch again to join.

Installation switch, electrical outlet prepares:

The lead put apart that go out will be swung to maintain length inside the box first, cut a Xiang Xin. Press lead the clockwise voluminous in switch, on the wiring column with corresponding electrical outlet, come back next close pressure head. If be odd core lead, also can insert line core tie line aperture directly inside, reoccupy carries filar general on the head its impaction. Notice line core must not appear.
