This invention belongs to the branch of electrical engineering, namely the sphere of electricity consumption recording units, which can be used in houses and other objects. The propaedeutical recording panel consists of a rectangular housing with locks on the doors; the edges are bended towards the inner wall of the housing and comprise a double bead, which supports the closed door. The top wall of the housing has an additional declivous roof, which comes above the roof through the whole length and width of the door. The supplementary cable covering, the size of which corresponds with the width and thickness of the housing, is fitted to the bottom wall of the box. This covering has an opening, which goes to the back part of the housing and the housing is inclined toward it. As a standard, connections for electricity counters and knife-switches come in the shape of the letter "T", longitudinal notches are made in them, the stripes at the back wall of the box and inside it are fitted at a distance equivalent to at least the length of used bolts from the surface of that wall. Inside the notches of tracking stripes, from the side of the back wall, the nuts are fitted in and linked by holders from the other side of the notches, which enable the nuts to move along the notches, the bolts with spacers are screwed inside the nuts. In the second version, the tracking stripes are placed in parallel with each other in pairs, in them the longitudinal notches are made. On two neighbouring stripes, the third supporting stripe, which has longitudinal notches, is placed perpendicularly to the notches of the tracking stripes, bolts with spacers are fitted in their crossings, screwed into nuts, linked by holders. On the back side of the box, from the outside, at a distance equivalent to at least the diameter of the incoming and outgoing connection cables, the fitting crossing in the shape of letter "H" is fitted; it must have notches longitudinal to the tracking stripes, the bolts are fitted inside the notches, which fit the recording panel vertically onto the wall or any other surface of the object suitable for this purpose. |
