Enclosure Surface 21-way (ES21)

This has been made for upgrading older “Teubels” meter boards from porcelain fuses to standard DIN rail mounting components. The ES21 solves the problem of limited depth between the panel and the cover prevented the cover from closing.

The enclosure is designed to fit onto 18” 453mm wide panels with the back on the MCB’s etc against the panel. By bending the mounting points back as shown in red in figure 1 the front of the MCB’s is 3mm from the front cover with the cover on. The enclosure is kept away from the hinge point to allow the panel to open.

Figure 1 (Top View)

NB. The ES21 is mounted on the right of the panel to improve the panel opening.

The ES21 has a capacity of 21 way which is enough for: Main switch, Water heating MCB, Oven MCB, Sub-main MCB, 3 RCD’s with 9 protected MCB’s, plus 2 extra spaces for other uses. This is adequate for the load requirements of most houses with this style meter board.

Fl ush Clip (FC1)

This two-part clip provides secure mounting for electrical fittings into wallboard 9.6mm to 13mm. To separate the parts release the ratchets from the inside. Then use the template markings on the base to mark the hole cut size on the wall. This will give the main hole size, two cuts will need to be added for around the mounting screws. The base can then be inserted into the wall and the front added to hold the base in place until the fitting is attached.
