Old-style ceramic switches in distribution boxes

Ceramic knobs were cylindrical and generally nailed directly into the wall studs or floor joists. Most had a circular groove running around their circumference, although some were constructed in two pieces with pass-through grooves on each side of the nail in the middle. A leather washer often cushioned the ceramic, to reduce breakage during installation.

Standards for the On-site Use of Distribution Boxes

The IEC (International Electrotechnical Commission) and BS 7671 (British Standard for Electrical Installations) both provide essential requirements for electrical installations, including those for fuse boards like garage unit, consumer unit and distribution board. This document sets forth technical, installation and safety specifications for distribution boxes, switch boxes and cabinets. These devices shall be of sound construction, water tight and not subject to excessive corrosion. 3 to BS 7671:2008 (IET Wiring Regulations Seventeenth Edition), which was published in January and comes into effect on 1 July, will include a new regulation requiring consumer units and similar switchgear assemblies in domestic premises to have a non-combustible enclosure.
