Why use a AFCI? An afci is not needed per
say, but if there is any exposed wiring in high traffic
areas for example a T-104 set up on the wall next to a
door, STJ cords running along the ground, cable inside a
cab to some duplexes that kind of thing, then I would
install one. They are only like $35 and I\'ve seen them
(rated) up to 40A.
AFCI stands for
Arc Fault Circuit
AFCI's are a very
neat safety device that have the ability to prevent:
Low level arcing cause buy high moister, dust or
impaired wire insulation.
Shorts from ground (Exp: exposed hot contacting a
Shorts (Exp: sudden large power surge from hot
Normal curcuit breaker, shuts off the power to a
circuit overheated wires from an over load.
Note: circuit breakers are thermally activated.
They trip if power going thru them exceeds their rating.
The breaker contacts heat up and trips. This can take
time, depending on the load.
Note: ground shorts
and shorts can occur with both GFCI and AFCI, but the
damage will be minimal.
Used in conjunction with
a GFC receptacle, gives you some of the best protection
All AFIs come with instructions and
clear wiring diagram (some are different). They should
only be installed by a licensed electrician.
If you can install a breaker and run a
circuit here is a stealth tip:
If you live
in a home, or have had a bed room circuit upgraded since
2002 (USA), there is most likely an AFCI in your breaker
box for each bed room (To avoid some one asking why you
have 3 afis in a two bed room house)
use a regular breaker in the main panel, then run a
small sub panel for the afi, (see pic below). That is an
option you can take. This can also function as a main
cut off for a small to med sized grow.
