      How to determine the size of the Single Phase E- Meter Box:
      The calculated size of this method is generally larger than the actual size.
      1, when the Single Phase E- Meter Box is only the Single Phase E- Meter Box or small power, the line is less than 10 square feet, if the switch is less than 20 bits, the width of the switch plus each side plus 20MM on the width of the box, the height of the switch height Plus 40MM, the depth of the maximum depth of the switch plus 10MM.
      2, when the Single Phase E- Meter Box is only the Single Phase E- Meter Box or small power, the line is less than 10 square feet, if the switch bit is greater than 20, when the Single Phase E- Meter Box needs to be arranged for the two rows of switches, switch width size plus each side plus 40MM for the width of the box, the height of the switch height plus 40MM, the depth of the maximum depth of the switch plus 10MM.
      3, when the Single Phase E- Meter Box is only the Single Phase E- Meter Box or small power, the line is less than 10 square feet, if the line switch needs a single row, the switch width size plus 20MM on each side for the width of the box, the height of the switch Height plus line switch height plus 40 MM, the depth of the maximum depth of the switch plus 10MM.
      4, when the power box for the power box, or power lighting box, the algorithm is basically the same as above, but when the line is greater than 10 square feet, to consider the line of bending radius of a terminal to set aside enough space Into the line, when the two rows of switches, should consider the wiring of the switch wiring.
      Of course, the size of the box is not conclusive, to consider the actual installation, depending on the actual wiring diagram and consider how to arrange the switch layout of a switch line.
      If all the miniature circuit breakers are determined according to the number of bits (18mm each), the PZ series Single Phase E- Meter Box has a fixed size, the circuit can be identified in the drawings identified by Party A (words), equipment control box identification equipment comes with, Line greater than 185mm2, the output is greater than 2 as far as possible use cabinet and so on.
      Leakage protector (leakage circuit breaker) wiring and installation of leakage protection of electrical equipment, the leakage current is extremely sensitive. When the human body exposed to the leakage of electrical appliances, the leakage current as long as the 10 ~ 30mA, can make the leakage protector in a very short period of time (such as 0.1s) trip, cut off the power, effectively prevent the occurrence of electric shock The Leakage protector also has the function of circuit breaker, it can be in the AC, DC low voltage circuit manual or electric split circuit.
      1. The wiring of the leakage protector must be connected directly above the leakage protector, that is, the "power" or "wire" end on the housing; the outlet is connected to the bottom, that is, the "load" or "outlet" The If the incoming line, the outlet is reversed, will lead to protector action after burning the coil or affect the protection of the connection, breaking capacity.
      2. Installation of the leakage protector (1) The leakage protector shall be installed in a switchboard with a smaller cross section or in a plastic meter box. Installed after the watt meter, before the fuse. (2) All lighting line conductors (including neutral wires) must pass through the leakage protector, and the neutral line must be insulated from the ground. (3) should be installed vertically, the inclination should not exceed 5 ° (4) After installing the leakage protector, can not remove the single-phase knife switch or fuse. This is a maintenance equipment when there is a clear break point; the second is in the knife or fuse plays a short circuit or overload protection.
