Hi. Hope someone can give an idea on what's going on. Purchased a
digital time to be installed to control the bathroom fan. The timer is
made by GE and suppose to replace a single pole switch. The timer
comes with 3 wires.
Black - circuit's line conductor
Blue - circuit's load conductor
white - ircuit's neutral conductor
My current switch box/plate has two switches (fan and light). I
opened it up and there are 3 sets of wires(black and white coming out
of the wall. The 3 white wires are connected together? The first
black connects to the top of switch one. The second black connects to
the top of switch 2. The third black conects to bottom of switch one.
There is another wire that connects the bottom of switch 1 to the
bottom of switch two. I hope this make sense. Can anyone tell how
that relates to line, load and neutral or how to find out. Your help
is much appreciated.
The 3 white wires capped together is your neutral. The white wire from the
timer goes with these.
That's the "load" for whatever switch 1 controls. If it happens to be the fan,
that's what you'll connect the blue timer wire to. If switch 1 is the light,
That's the load for switch 2. If it happens to be the light, disregard. If it's
the fan, that's where the blue wire from the timer connects.
The black that connects to both switches is the line. That's the power that
feeds both switches. (Which is why it's jumpered to the other switch as well.)
This is the wire that must still connect to a switch for the light, but must
also connect to the black "Line" wire for the timer.
Note that there is no "standard" as to where on a switch the line and load
connect, could be either top or bottom.
That sounds like a normal set-up for a 2 switch system for fan and light.
Find the switch that works the fan and take the wires off of it. Of course,
turn of the electricity before disassembling the wiring. Then, connect the
hot wire -- the one that is jumpered to the other switch, to the Black -
circuit's line conductor. Connect the other wire to the Blue - circuit's
load conductor. Then, connect the White - circuit's neutral conductor to
the other Whites in the box.
