All these items may be determined by contacting suppliers of <...Single/ Double/ Dead front electrical Panels...> directly, as CR4 does not provide such a service.

<...Hoping...> Hope is not a strategy. Why wait (rhetorical question - NNTR)?

How did the telephone calls with equipment suppliers go? This feedback will prove valuable for other readers interested in this topic going forwards as a learning exercise. However it would prove indelicate to reveal commercially-sensitive financial information or suppliers' names.

Lyn:- your comment is no doubt correct, but I just tried it and this thread is currently the no.1 on google :-)

For reference of anyone new to the industry, here are some simple descriptions when applied to switchboards, control panels, motor control centres etc:-

Single front - one designated with a front and rear i.e. all the controls and indications at one side (the front) with the rear blank or used for cables only.

Double front - sometimes called back-to-back, controls front and rear, will usually contain vertical cableways along the length of the board. Advantage is shorter length which may translate into lower cost (especially of busbars). Disadvantage is more difficult access especially maintenance.

Dead front - old fashioned term, related to when "open" knife switches were mounted on marble slabs, for instance, hence moving towards a "dead front" with everything live hidden behind a single panel. When I started work in the late 70's many old plants from the 50's still had DOL starters mounted together in rows on a wall (e.g. Allenwest SC1). Not sure what this practice was called but pictures are hard to find these days.

The quickest way would be to contact a switchboard manufacturer and ask them, they should be able to give you a quick answer if all you are after is a rough idea of the price variation between the different options.
