Installed timer and I'm getting breaker pop. I've tried several different ways to wire and it keeps poping the breaker. GE Replacement Timer 15600


1) If you are replacing T103, the T103 can be wired many different ways. Not all wiring diagrams are supported by GE 15600 replacement timer that fits into Intermatic box.

2) Double check your T103 terminals
T103 terminals should be A 1 2 3 4
If terminals 3 and 4 have wires, then GE is not correct replacement.
You can buy repair parts for Intermatic timer
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

3) GE has terminals 1 and L which are connected by brass bridge. If brass bridge is removed, add a jumper wire and connect terminals 1 and L
GE has terminals 1-L X 2

4) Typical GE 15600 wiring shows on following link, in addition to links for parts and manual:
http://waterheatertimer.org/GE-timers-and-manuals.html#15306

White wires on terminal A connect to terminal X
Black wire on terminal 1 connects to terminal 1
Black wire on terminal 2 connects to terminal 2

What is the correct way to hook up a TM813-WCCS? I have one lead from the downstairs 3-way switch - black/red/white, and a fan lead - black/white. I can get the 3-way switches to work, but no luck adding...


Not enough information is given.
TM813 is combo switch with single-pole and 3-way. So switch has two different rocker-switches on face, and one controls 3-way circuit and one controls single-pole circuit.
You are controlling a light and a fan.
You have successfully connected lights to 3-way switch.
Are you trying to connect fan to single-pole switch?
Add a comment and say what you are connecting, and what type of switch you are replacing, and what each wire tests, and what terminals are on switch and what wire you have connected to each terminal so far.

Hi There, I have a Marantz SR7005 Receiver and Bose 901 Series VI speakers with the Bose equalizer. I'm struggling to figure out the best way to connect the Bose equalizer/speakers to the SR7005. ...


It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

Is it bridgeable


yes you can bridge this amp to one channel
here are the specs for the amp
  • stereo or bridged mono output
  • Tri-way capable (Tri-Way crossover required)
  • 100 watts x 2 at 2 ohms
  • 200 watts x 1 in bridged mode
  • requires 10-gauge power and ground leads — wiring and hardware not included with amplifier
  • PWM MOSFET switching power supply
  • Intelligent Surface Mount Technology for cleaner sound and greater reliability
  • selectable 85 Hz high-pass/low-pass crossovers, 18 dB/octave
  • preamp outputs
  • speaker-level inputs with SmartEngage (turns the amp on when it detects signal from the receiver, eliminating the need for a separate turn-on lead from your receiver)
  • 9-3/4"W x 2-1/8"H x 9-3/4"D

    Is there a wiring diagram for the nikkai EAPA450 Amp


    Hi, if you still need a photocopy of instructions email me mail@srands.co.uk

    If you want instructions in brief this involves POWER CONNECTIONS, PHONO LEAD & SPEAKER CONNECTIONS:

    POWER (At the same time when routing these wires, I would connect the PHONO LEADS from the car cd player to the amp, if your car cd player only has 1 preout (1red & 1 white) then you will need two phono splitters, a female to 2 males. Phono leads carry the unamplified sound from cd player to the amp):
    ~ Permanent 12V+ (Thick lead that is fused direct from battery all the way to the amp, wire must be 20a to 30a +, hence 1cm diameter wire, known as AWG8, Maplin sell cheaper kits then most)
    ~ Amp REMOTE (A thin insulated cable (5a is OK) from car cd player amp remote wire, this turns the amp on when the cd player is on, if your car doesn't have an amp remote wire, suggest nearest ignition supply or seperate switch that you turn on when you want to turn on the amp)
    ~ GrouND 12V- (Insulated lead (20a to 30a) to nearest part of unpainted car chassis such as interior panel screw hole, instead of an insulated cable all the way from the batery, this is common practise.

    SPEAKER:
    Each speaker has a - negative & + positive, these must connected correctly. The amp has 4 channel, 2 channel labeled as front, 2 channels labeled as rear. Using speaker wire, connect cable from amp to speakers. Note: Ensure the speakers being connected only receive sound from the amp (Not cd player as well, as would damage players or at the very least impair sound)
    The amp has a feature called bridgeable this means a sub 8" or 10" sub can be powered by 'bridging' two channels. For example there are 2 ways to bridge power a Sub on the NIKKAI EAPA450:
    i) Sub speaker wire positive + to channel RL and Sub speaker wire negative - to channel RR.
    OR
    ii) Sub speaker wire positive + to channel FL and Sub speaker wire negative - to channel FR.

    Switches:
    ~ Bass boost, meant to be on for a channel if using sub, otherwise off.
    ~ X-over mode adjust hi/lo frequencies, only work if both x-over switches are on! Then adjust switch frequency knob, until it sounds right.
    ~ Gain (Volume knob) adjust volume knob up or down, until it sounds right!

    NOTE:
    You will need patience! many hand tools and parts such as: Wiring kit, fuse holder 20a/30a, Phono leads, speaker cable, Fork/ring connectors, wire strippers, wire cutters, set of screw drivers, also ueful to have zip ties to tdy excess cable and 'P' cable clips to tidy speaker wire to shelf, etc.

    OK

    Any more questions just email me mail@srands.co.uk

    Connect subwoofer etc to nad 3020I stereo amplifier


    Hi Info
    You can use a 2 x male RCA to RCA female adaptor lead(what you need to ask for)  like this one 4d0dcde.jpg

    use it to jumper your pre-out/main in connection on the rear, and connect an RCA lead to the Female socket on the adaptor lead. That will get you going. You can get them most places that sell electronic bits and peices. I am happy to answer any questionsa you may have

    Installing a amp with my kenwood mp338 receiver


    You shouldn't need any special adaptors. You just have to connect the RCA cables and the remote turn on lead to the receiver and then to the amp.

    Possibly an internal issue in the amp (i.e. broken solder joint on the circuit board). Also, check your RCA preout connections, too.
