0 rows row size: 10-1000 (mm) material: brass features: rigid applications: zero rows of grounded
0 rows row zero rows row specifications, dimensions can be customized processing
0 rows row selection, distribution box zero rows row selection is based on the main line switch power supply to choose the size, zero-emission capacity cannot be too small, low-voltage power distribution can be found according to the specification details. Neutral ground under the general lines of the same size or slightly smaller than configured. Zero line cross section area of two-thirds.
The main grounding bus bar is stress. Lightning protection systems, common ground bus installation in the engine compartment in front of the net, on the ground and into the pool raft on the grounding of all equipment in the room. If there is too much room, and under the static floor grading rings produced, equipment grounding conductors and earthing wires connect to the pressure ring on the floor. This is done in order to prevent potential combat health, the so-called elevator pressure equipment, no potential difference.
Distribution box has four lines: 1, line (l). Electric energy transmission conductors, normally grounded.
2, neutral wire (n). Connected with the system of neutral point, and can transport electric energy of the conductor.
3, protection of neutral line (PEN). Both protection line and neutral conductors.
4, power point. The power grounding point (usually the neutral) earthed.
In General, the neutral and ground the primary distinction is that an integral circuit, a protection called protective earth, a power supply network, a return to Earth, in the electronic circuit is to distinguish these two concepts in formal circumstances required by these two lines to separate. Drainage needs connected with the distribution Cabinet shell, after GFCI ground zero for zero rows. Cognitive method is simple, straight copper wire is zero rows, bent copper bars for drainage
. Distribution cabinets, 0 and row is sense. This is what Ah Solution 1: In a Word, please recognize stress range Museum Yi Huan GUI Hai Li really learn grounding system.
In scene 1, if it is TN system, be sure and zero is the same; 2, if not in the field, apart from isolating transformer in armed Renaissance outside the zero-sum info, the other is zero and no sense.
Solution 2: Distribution Cabinet of the new zero line and ground should be different for two lines, is unreasonable, if it is connected into the stress range Guan Yi hwan turtles only terrible drain lines then the two lines are the same because the transformer neutral and ground wire connected at the top with an earthing terminal. If this is a new distribution cabinets of two lines are not connected, if the same action will result in leakage protector, switch is not working properly.
Solution 3: Field zero rows of Unicom is normal, especially in the transformer room, because most of the transformer center point (neutral) ground, n systems, more
Solution 4: Should not be shared, if insulators are broken, if not may be motor ground wire on a device (a device has multiple motors) received, on the zero line, and the grounding line, and must be promptly corrected.
