He's using an ancient adapter for non-grounded circuits. Many of them
predate the wide neutral blade.

The proper solution is to not use those adapters.

Yeah, just cut off the ground prong instead...

Or just replacethe outlet - replace with a GFCI if there is no ground
available and document it as required by code


whooosh...

Sounds like a plumber commenting on electric work.
Clare is right.

406.4(D)(2)(b) A non€“grounding-type receptacle(s) shall be permitted
to be replaced with a ground-fault circuit interrupter-type
of receptacle(s). These receptacles or their cover plates shall be
marked €œNo Equipment Ground.€� An equipment grounding
conductor shall not be connected from the ground-fault
circuit-interrupter-type receptacle to any outlet supplied from
the ground-fault circuit-interrupter receptacle.
