Anything plugged into it? A Surge protector can cause this.

Does the generator require you connect the gender to ground from a lug on the side? It may be expecting this.

It really depends on what load is connected.

If theres no load connected (gen only) call customer service.

open ground=ground wire (green) is not connected to the circuit box ground or to the earth ground.
(there should have steel rod place in the ground by the local electric company, and gtound wire is connected to that rod).
Open Neutral= same as open ground. unless you are testing 240V, which have 2 hot (110v) and a neutral (0V).
Open Hot= open 110v line (black)
hot/ground reversed= if you understand the above, then this sould be self explaintory.

SOURCE: what does open neutral on my gb circuit tester

An open neutral means that neutral, or common wire is not connected somewhere. If for example you test a outlet in a room, and the tester shows that you have an open neutral, Then somewhere along the circuit the neutral is not connected properly. In rooms most outlets are connected in series to each other, so if you have an open neutral in one outlet, it can affect all the other outlets too.

Hot/ground reversed means that the hot wire and the common wire are installed in the wrong order.on the outlet,you have a hot side (black wire)and a common side(white wire)and the hot wire is installed on the common side instead of the hot side and the common is installed on the hot side.This show up on the tester this way because the common and ground tie into the same bar in the panel.

Fix the open neutral first as this can show incorrect reading on the tester on all outlets after the open neutral.

SOURCE: manual transmission stuck in reverse in my mx-5

You will have to remove the center console and then the shifter asm. look down inside where the shifter goes and you will see 3 selectors one will be out of position. You will need to pop it back inline with the other 2. After that look at the bottom of the shifter ther should be a bushing on the very end, if it is not there you will need to get one from your dealer, they are like 8 dollars and then you just pop it on and reasemble in reverse order and you should not have any more trouble.

SOURCE: Mini Split Heat Pump wiring

Check to make sure it is single phase, should be stamped on unit. Is this wiring coming from what use to be there?

If you replaced the old unit with this one, you can trace the wires back to the breaker box. If you are Electrically inclined or you know someone who is.
Remove the panel and trace the nuetral and ground wire to the bus termination.

Some States require or use to require that the nuetral
and ground wire be tied together. 230 is 230v ,2hot and a ground.

My guess is you tie nuetral and ground together or
I wouldnt use white wire and I would disconnect
from both ends.

If you are uneasy about electricity, talk to a certified
electrician. Contact City Electrical Inspector. Dont get hurt!

Outlets do not work, circuit tester says Hot/ground reverse but all connections appear correct, circuit is on an arc arrest breaker.

Move wires to different breaker with same amp rating?
Try different tester?

I have a Precor 9.45 I that states error 10 what is wrong with it

Precor Error 10, Line Frequency out of Acceptable Range Probable Cause 1. Treadmill is connected to a non-dedicated AC circuit
2. The AC hot and AC neutral wires are reversed on a 120VAC circuit.
3. The upper PCA has an incorrect jumper setting.
4. Fuse feeding the stepdown transformer is bad.
5. AC line frequency is incorrect.
6. AC line may be excessively noisy. Corrective Action
  1. Treadmill must be connected to a completely dedicated 20amp AC circuit. Both hot and neutral leads must be dedicated to the treadmill. If the circuit is shared with another piece of equipment, it can cause enough electrical noise to make the AC line frequency impossible to identify. The AC circuit for the treadmill must be re-configured as a completely dedicated 20amp circuit.
  2. Many line frequency detection systems observe the AC line frequency on the hot AC line. In the event of a reversed 120VAC circuit, the observation is taking place on the neutral (ground) part of the AC line. Many observing systems are not capable of detecting line frequency on the neutral line. First it must be determined if the reversal is in the AC wiring feeding the treadmill or in the internal wiring of the treadmill. The hot and neutral lines can be confirmed by measuring each in reference to AC (green wire) ground. The hot wire will read full line voltage (commonly 105 - 120VAC) and the neutral should read about 0VAC.
  3. The upper PCA's for some units had a jumper setting for use with SCR or PWM drive circuits. If the jumper was set on the upper PCA as PWM on an SCR unit, the Error 10 appears. Change the jumper setting to SCR to correct the problem.
  4. A pair of fuses were used on some treadmills (C944 PWM version 2 and C96x PWM version 2) that fed the stepdown transformer for the low voltage power supply on the lower PCA. The AC line frequency was observed on the output of one of the fuses. If the fuse blew, AC line frequency could not be detected even though the treadmill appeared normal under other circumstances.
  5. It is unlikely, however, the AC line frequency could be out of acceptable limits. This would more likely occor in countries were AC power systems may not be well developed and controlled. There is little that can be done to correct this issue. If the source frequency cannot be corrected, the only possibility would be replacing the treadmill with one that utilizes a PWM motor controller. PWM motor controllers do not depend on line frequency for speed control.
  6. At times the AC being fed into the distribution system is too electrically noisy to allow correct line frequency identification. This can be caused by other equipment within the AC distribution system creating the electrical noise. It can be difficult to identify the source of the electrical noise. There is little that can be done to correct this issue. The source needs to be located and removed or made electrically quiet. If this cannot be done, the only possibility would be replacing the treadmill with one that utilizes a PWM motor controller. PWM motor controllers do not depend on line frequency for speed control.

SA 150 20 MP TIMER--- I have a manual timer in place now which does not always shut off. It is wired in with Black and Red wires and green to ground. The diagram on this new unit is confusing me Help...

Open following link to identify SA150 single pole 15-minute countdown timer rated for 1 Hp
http://waterheatertimer.org/Sylvania-timers-and-manuals.html#countdown

Timer has 3 wires:
Timer-Black wire connects to Hot from breaker. One of the old switch wires is Hot. Hot is usually black wire, and will test for 120V when tested to ground wire.
Timer-Blue wire connects to Load wire going to light/fan/motor. The Load wire is other wire that connects to old switch.
Timer-White wire connects to white Neutral wires. This will power the timer electronics. Neutral wires are the white wires that are twisted together and covered with wire nut and pushed to back of box.
If box does not have Neutral wires, then connect Timer-white to bare ground wire until you have time to bring neutral wire to box from any nearby outlet. Wiring timer to ground in this manner is not code.
Turn power on. If timer does not work, then reverse Timer-Blue and Timer-black and see if timer functions correctly.
If Sylvania timer will not function, then call 888-548-4484

If you want electronic countdown timer that requires no neutral wire, then select 1 Hp spring-wound timer, or 1/6 Hp Leviton-LTT series

1/3 Hp 115 volt 24 year old motor 40 amps. single Phase. is this for 110 volt Plug in to wall.It also 3 wires , Orange,Red, White, were do i hook these up to on a 110 Plug. Can you Please help.

You looked at nameplate on motor to get the rating information?
Rating plate may also have small wiring diagram.

I was looking at AO Smith single-phase 2-speed pool pump motors yesterday.
The rating plates show wiring.
Open following link:
http://waterheatertimer.org/images/AO-smith-rating-label-500.jpg

Notice the image shows the words: Brown White Line Line.
Brown and white are wire colors. Line means 'power' from breaker box.
240V will have two Line wires, L1 and L2. 115Volt will have Line or L1 and N or Neutral.
Look at your rating plate and then add a comment with clear description of what appears on rating plate, or include in-focus photo. Put your camera in macro to take close-ups.

Your wall outlet has 2 plug-in slots. One is wider that the other.
'Line' will refer to Hot wire from breaker which corresponds to smaller slot on outlet.
'N' or 'Neutral' is neutral wire from breaker box which corresponds to wider slot on outlet.

New switch GE model 15265 ... to light up 2 lightbulbs outside. Old switch all cables are black. Those who light up the tester are the hot=Red/black?? Those which do not light up are white?? Green I know...

Manual for GE 15265
http://waterheatertimer.org/pdf/GE-15265-manual.pdf
15A timer works fine on two bulbs, up to 1440 total watts.

If old switch has 2 screws plus green ground screw, then timer is right.
If old switch has 3 screws plus green ground screw, 15265 doesn't replace 3-way switch.

Timer-green wire connects to bare ground wire

Old switch has 2 screws with wires on each.
One wire is Hot-from breaker and this connects to timer-black wire.
One wire Goes-to-lights and this connects to timer-red wire.
If you get these two wires reversed, timer will not work, so reverse them.
It will not blow circuit if the timer-red and timer-black wires are reversed.

Timer-White wire is the confusing wire for everybody:
Timer-white wire runs clock motor located inside timer.
In back of electric box are neutral white wires that are twisted together and covered with wire nut.
Connect timer-white to these neutral wires.
If box does not have neutral white wires, connect timer-white to bare ground wire.

I am replacing an old intermatic model EJ341 spring wound timer with a GE15086 digital in wall timer. The old intermatic timer has two black wires from each side (I dont know which one is hot). Each of the...

GE 15086 is a 7-day programmable timer. It has more wires than spring-wound timer because clock motor runs on 120V circuit, just like ordinary electric clock. The clock on spring wound timer operated by a spring.
f7d4104.jpg


If I understand correctly, the old timer has 2 wires. One of these wires is the Hot wire ... and that wire will connect to GE timer black wire.
The other wire from old timer goes to Load ... and that wire will go to GE timer red wire.

Instructions on a lot of these timers say, it timer doesn't work, then reverse the two wires described above ... this is because timer only works when Timer black connects to Hot.

You can also turn on power and test each wire that came off old switch to bare ground wire. When tester lights up, that is Hot wire.

GE timer Green wire connects to bare ground wire.

Moving on to GE timer white wire. This wire is necessary for the clock to run. This wire connects to Neutral wire which is usually white. You can test for Neutral by testing Hot wire to each white wire in box ... when tester comes on, that is Neutral.

If you do not have a white Neutral wire, then connect GE timer white wire to bare ground wire. This is not code, but it will work fine until you hire electrician to run Neutral into box.
