Lamp Holder Adapter.

If they are the early dry element type, where an element takes the form of a very flat wire wound resistor (a copper bar with mica sheets, then a wrap of nichrome rather like the old glow wore fire elements, then more mica),  sandwiched with a couple or wing nuts into intimate contact with the underside  of an otherwise ordinary kettle, then it may be for 200V DC ?

Some designs were with 2 elements in series, for 200V  so it can re configured for 100V or so by removing the cover and moving a link, so putting them in parallel.


Assume 6- 8 amps on 240V, or  more like 4 to 5 off 200V and twice that in the 100V setting.

Just because there is a bayonet lighting adapter does not mean that you cold not plug in a 10A load on a 5A hot wire fuse, if you are only a few minutes about it.

EDIT beware - there might be asbestos instead of mica on the wire element.
