consumer unit electrical enclosure Introduction:
Plastic consumer unit, which is suitable for all kinds of residential house, villas, residential areas, etc,which is divided into surface and flush mounting installation.And accord with IEC 60439-3 international standard.The box body and panel are made of flame retardant ABS material. The small circular arc door can open up to 90 degrees.With galvanized din rail and adjustable support,the depth of din rail can be adjusted to install different size MCB and RCD.
First, improve the environment of the distribution room.
1. The lighting in the power distribution room is good enough and the ventilation equipment is good.
2. It is strictly prohibited to pile up sundries in the consumer unit electrical enclosure power distribution room, so that indoor equipment does not accumulate dust, oil mud, the ground does not accumulate dust, no water, and the environment is clean and neat.
3. The indoor environment temperature of the power distribution room should not exceed 40 degrees, and the relative humidity should be less than 80%.
4. the distribution room roof, underground water leakage phenomenon, drainage unobstructed, and pest control, rodent control facilities should also be improved.
5. the distribution room to do waterproof layer processing.
Two, install dehumidification equipment.
Install the dehumidifier, the fan will pump the moist air into the machine, through the heat exchanger, at this time the water in the air condense into water droplets, become dry air out of the machine, so that the indoor humidity is reduced by circulation.
1 At the entrance of the power distribution Consumer Unit Electrical Enclosure room , generator room, fire water tank room, water pump room, fire control room, etc., identification signs and warning signs of "no entry unless you are a worker" should be set to distinguish them from other rooms.
2 The power distribution cabinet (distribution box) of fire-fighting facilities should be set to distinguish it from the power distribution cabinet (distribution box) of other facilities; the power distribution cabinet (distribution box) of the standby fire-fighting power supply should be set to be different from the main fire-fighting power distribution cabinet (Distribution box) identification; the power distribution cabinets (distribution boxes) of different fire-fighting facilities should be clearly distinguished.
3 Permanently fixed identification signs and warning signs of “no pressure buried or occupying fire-fighting facilities” should be set up in places such as fire-fighting pools, water intakes or wells, valves, water pump adapters, and outdoor fire hydrants for fire-fighting vehicles to take water.
4 The pipes, control valves, and control cabinets of fire water tanks, water tanks, stabilized pumps, booster pumps, air pressure water tanks, fire water pumps, and water pump adapters shall be provided with prompt signs and distinguishable identification signs.
1. In fire and explosion hazard places and distribution lines that may be overloaded for a long time, overload protection devices should be installed. The allowable current carrying capacity of insulated wires and cables of distribution lines should not be less than the rated current of the fuse melt Or 1.25 times of the setting current of automatic switch long-time overcurrent tripping.
2. All metal parts of the distribution box that are not charged under normal conditions must be reliably grounded (zero).
3. The socket wiring in the distribution box should be correct. There should be obvious differences between AC and DC or no voltage sockets, and each switch and each group of fuses in the box should have a sign diagram indicating the controlled object.
4. The floor-type low-voltage distribution box installed in the workshop should make its bottom higher than the ground, and the minimum distance between the front and rear of the box from other facilities is not less than 0.8 meters.
5. When the open-type low-voltage distribution box is selected for the site, if the height of the unshielded bare conductive part is less than 2.3 meters, a fence should be set up, and the clear distance from the fence to the bare conductive part should not be less than 0.8 meters, and the height should not be Below 1.2 meters. Other exposed components that may be touched within the operating range should also be shielded.
