Another electrical protection device is called an AGFI. This is a
GFI now required for all bedrooms. It detects electric arcing; cuts
off power before a fire can occur.

It is AFCI - arc-fault circuit interrupter. They are much more
sophisticated than a GFCI, They detect *only* “parallel” arcs, like line
to neutral. They do not detect “series” arcs, like a loose connection.
(“Combination” AFCIs that detect series arcs are required after 1–1-08
but they probably don’t exist now and may well not exist then.)


A newer type of GFCI that also quashes electrical arcs.
Available in any electrical supply or hardware store.

Provide a link with information for this mythical device.
