I have an old K&T meter as office cha cha, two little holes in, two out. This came from an exposed situation one could walk up to.

In fact, much of the first 'wired after it's built'places in New England had exposed K&T

my code book collection only goes back to the 50's, so i'm just guessing that any exposed to physical damage references may not have existed

much of the K&T run back then was in wooden wiremould, but some of it, for instance in grange halls , or manufacturing shops, remained exposed on porcelian knobs or porcelian tubes

my take is the issue was more esthetic than anything else

in fact, the old mill being renovated in Springfield VT had exposed tubes with an I.D. of over 1" for fat copper 3phase conductors , which they just tapped off of into fuse-only museum worthy panels

We were watching an old 1934 Gable movie and they had a switch on the wall with two wires coming down that looked like K&T but it was a surface run.


I Stumbled across an episode of Hogan's Heroes last night, where Colonel Klink was, once again, nearly being sent to the Russian Front for Combat duty.

During the scenes, when Major Hocksteter (Sp???) was tearing Klink a new one, the Camera angle showed the Entrance Door to Klink's Office.
On the Right side of the Door, is a Surface Mounted "Rocker" Switch (Two Push Buttons; One for "OFF" at the top, One for "ON" at the bottom).
The Switch is connected via exposed, Surface Mounted Wiring, in the form of a Two-Wire twisted pair of Brown Insulated Conductors, possibly #14 Gauge.

The outcome for Klink was typical; Hogan's Sabotage Unit got Klink cleared of the Charges, then made Hocksteter a Hero - which kept Klink away from the Sub-Zero Frontline gig; and all was happy once again.

I think I have seen that K & T wiring on M*A*S*H years ago. I will have to look for an old episode.

I have also seen K & T wiring placed in a wood molding that ran down alongside the door frame and the wire was laid inside of it. Then it would pop out and on to a switch that was surface mounted.

The twisted exposed wiring was pretty common back in the day.
This example is still live (230V) and used pretty much daily (light switch for an enclosed porch).

Blends right in with the door frame, doesn't it?

The wooden wiremold seems to have been more of a UK/Ireland thing, sometimes it can still be found, such as in the Belfast Hostel Paddy's Palace in 2008:

As you can see, the electricians didn't want to touch the plaster crown moulding and just ran the individual conductors exposed.
