Porcelain lamp holders -- all installs code violations?

[iwire]

But remember that the 90 degrees is only for 'derating purposes,

Not just for derating, also for connection to devices or fixtures that require 90C conductors as we have here.

in the end you still have to have the 60 degree ampacity, 334.80.

I agree.

A keyed type lamp holder actually had what appears to be a key switch on it:

In the olde days, it was common to see this type of lamp holder hanging from a pendant in the middle of a room. One had to turn the "key" to make the light come on. Pull-chain types were later used, so the light bulb could be mounted closer to the ceiling ....

Ive remember well and some rooms had no receptacles and they would install the extension adapter with a 2 prong outlet on each side , They would put the ironing board under the light and plug the iron it , the bulb would be swinging on every stroke :grin:

. . . and they would install the extension adapter with a 2 prong outlet on each side . . .

And before the adapter, the brass lampholder had the receptacle built right into it.

I was called to give an estimate at the estate of Fin who had lived till his death in the duplex that his mom and dad had built in 1905. The electrical was never touched. There were two receptacles per unit, one in the living room for the AM radio (baseboard mounted and beside a separate box for the antenna / ground) and the other was the single receptacle built into the side of the brass lampholder hanging on a 4' pendant in the middle of the kitchen.

Blew my mind.
