How do I wire and connect an
in-line duct fan?
Your In-Line Duct Fan must be
connected to a 110/120 Volt AC, 60Hz fuse or protected
by at least a 15amps circuit breaker. Never connect your
In-Line Duct Fan to a 240 Volt AC blower motor or other
240 Volt systems. When you remove the fan from its box,
there will be no cover box for the wires, as that is
only used when connecting the fan to a switch. For all
purposes we’re going to connect it to a heavy-duty
extension cord. A pretty simple procedure, most fans
come with either, 1 black wire, 1 green wire (ground),
and 1 white wire. To begin, simply slice the extension
cord wire. Make sure it has a ground plug (3 connector
pins). Then merely match up the wires, green goes to
green, this is your ground wire, white goes to white
,and black goes to black. You might run into a situation
where you have 2 black wires, and 1 green wire. Simply
attach the green to the green wire, and attach one black
to black, and the other black wire to the white wire.
is a wire-stripper-crimper:
Point A (the white arrow) is used for
cutting the wire ends off, just like a pair of pliers.
More than likely you will not have to do this, most are
pre-cut coming from the manufacturer (On the fan, and on
the extension cord). Point B is used for
stripping the wire, put the wire end in the proper gauge
hole (Marked on the tool), and pull. Point C is
used for crimping. In this assembly, I have used wire
nuts instead of crimped butt splice connectors.
You’ll need 3 wire nut
connectors, 1 for the white wire which is your common, 1
for the black wire which is your hot wire, and 1 for the
green wire which is your ground. After all wires firmly
connected with the wire nuts, it is a good electrical
safety practice to tape over the nuts using electrical
tape or duct tape. After each connector is taped, bundle
all three together and tape it over as one bundle.
You must never have any bare wires
Now all you have to do is plug it into the
outlet. And if hanging In-Line Duct Fans, make sure you
have them adequately supported, If you’re fitting the
fan inside a wall, wrap rubber around it to reduce the
noise level and stop vibration.
NEVER EXPOSE YOUR IN-LINE DUCT FAN
TO TEMPERATURES OVER 140° F (60° C)!
