Indoor Distribution Box

Introduction

This is indoor distribution Box which can be equipped with various modular electrics for the function of terminal power distribution. Polyester distribution box is widely used in low voltage distribution networks for power supplying of consumers and commercial buildings. Quality decides success or failure, strength casts dream.

This Indoor Distribution Box has transparent sanding window, which is safe and convenient to operate, and is easy to install and repair. The design of humanization can remove the baffle plate by itself, which can meet the installation of guide rail electrical appliances such as circuit breaker and subsequent expansion. It has strong impact resistance and high protection level. It uses high-quality flame retardant material to make flame retardant panel, to ensure the safety of electricity. Multi specification perforation combination, meet different installation requirements.

Testing the distribution box

Before doing the testing of the Indoor Distribution Box we need to turn off the isolator and RCCB in the distribution box. We must also cut the phase and neutral to the distribution box before doing the testing. If we didn’t cut the phase and neutral while checking the distribution box circuit then the meter coil will be damaged and the meter won’t work.

The black probe in the probe must be connected with a clip and this clip should be connected to the earth of the distribution box. Select the 250 range in the megger at this time we can see OL in the display which means that open link. After that connect the red probe of the megger to the neutral bus bar then a value will be displayed in the megger and the value will be in Megha ohms and this shows the insulation resistance. If the megger valve is zero when connected to the bus bar then there is a short.

After that test, check the phase wire of the MCB which is the outgoing wire, place the red probe of the megger in the MCB’s output and we can see a certain value and this will be more than a thousand mega ohms. If the value is zero then there is a short. Now connect the megger’s red wire to the main neutral and the value will be zero because the earth and the neutral are ground.

What are the precautions for the use of low-voltage Indoor Distribution Box?

(1) Equipment requirements

1) The appearance inspection of the distribution box body should be free of damage and deformation, and the paint should be intact. Internal inspection of the distribution box: electrical devices, components, and insulating porcelain parts are complete, and there are no defects such as damage and cracks.

2) Before installation, check whether the distribution box number is consistent with the installation position, and check the box number and the circuit number in the box according to the design drawings. The grounding of the box door should use soft copper braided wire and special terminal. The wiring in the box should be neat.

(2) Working conditions

The civil construction of the installation site of the distribution box should have the basic conditions that the interior painting has been completed and the doors and windows have been installed. Pre-embedded pipelines and pre-embedded parts should be cleaned up; the site has transportation conditions, and the road should be kept smooth and smooth.

(3) Distribution box positioning: According to the design requirements, determine the location of the distribution box and the actual equipment installation on the site, and locate the elastic line according to the overall size of the box.
