Dimmer switch with Hot & Neutral wire ?
i don't understand this network, seems it is wrong but seems to work just fine. maybe you can explain it?
i have 3 lights all running off one dimmer switch. there is a single 14/3 wire (red,black,white) entering the switch box. in the same box is another dimmer controlling a separate light (i.e. no 3-way switch here).
the white wire is wrapped in black tape, probably the electrician is giving indication that this white wire is being used as a HOT. it measures infinite impedance to ground (and to the other wires) so probably a good guess. this HOT wire goes to one terminal on both switches.. so far so good.
on the other side of the dimmer switch A is a red wire.
the other side of dimmer switch B is the black wire.
ok, no problem here either.. i am thinking that the RED and BLACK are also HOT, so the dimmer switch is interrupting only the HOT wire.
but when i measured the RED and BLACK wire with respect to the metal box i get 5 ohms, and it beep on my multimeter.
huh? seems each dimmer is wired such that it is in series with the loop. HOT wire and NEUTRAL connected to the dimmer.
the wiring is confusing me because it is against my conventional thinking of how wiring should be. my thinking is that switches should only interrupt HOT wire, never the neutral. this is for safety.
what do you think?
by the way, the light seems to work just fine.
