In one aspect, the present invention is directed to a distribution box, comprising: a distribution board; a shield protecting the electric components of the board; an aperture located in the shield; and a net covering the aperture, thereby allowing an infrared camera to scan the area wherein the electric components of the distribution are deployed, through the aperture, without removing the shield. In a preferred embodiment of the invention, the net filters less than about 50 percents of the beams reaching to the net. The net may be secured to the shield by an adhesive layer, bolts, and so on. In a preferred embodiment of the present invention, the aperture is a bore, preferably of a diameter of about 7.5 cm, thereby suitable for a common distribution box. Preferably, size of the net cavities is less than the corresponding size of a human finger.
