Hello. There are a few reasons the breaker may be tripping. If the glass in-line fuse has blown, a surge may trigger a pannel short. Check the solenoid for any visual hints that the solenoid has failed, such as rust, and recheck that all wire connections are still waterproof. If there is a short (due to water seeping in) that function of the program, when activated, will cause the system to trip. What does the system do at the 10 hr point after program runs? Another thing to check is the resistance through your transformer, if you see an infinite reading (numbers just keep going and going) then you will need to replace the transformer. I've located the RainBird help site for you and they will be able do go through the specifics of your system with you. The link: http://www.rainbird.com/homeowner/index.htm

Hope this helps you out, and please don't forget to rate us. Thank You.

Our 7788F keeps going into a ground fault condition. Need help troubleshooting. John


Ground Fault ???
Troubleshooting Ground Fault

Troubleshooting a ground fault circuit interrupt, or GFI, breaker is pretty straightforward. Troubleshooting the circuit itself can be quite time-consuming.
The GFI breaker is designed with a test button incorporated into the breaker itself.
Pushing the test button should trip the breaker.
On GFI-style breakers the neutral wire going into the house's outlets is connected to the breaker's neutral connector, the white neutral that comes out of the breaker is connected to the neutral bus in the panel, isolating the neutral bus from the neutral wire going into the house.
The test button actually shorts the neutral wire feeding the circuit to the neutral bus in the electrical panel creating a ground fault that should trip the breaker.
It is considered a ground fault because the neutral bus in the main electrical panel is actually connected to the ground bus through the panel's metal casing. What to do if the test button isn't tripping the breaker
1
Push the test button on the GFI breaker.
The breaker should trip.
If the breaker does not trip, then it may be that the breaker has already tripped and just looks like it's on.
The position of the switch may only move slightly from the on position towards the off position when tripped.

2
Push the switch on the GFI breaker all of the way toward the off position.
It may take some force to get the breaker to reset.
Turn the breaker back to the on position.
When the breaker has been reset properly you should feel some resistance when pushing the switch back on.



3 Push the test button again and the breaker should trip.
If the breaker still doesn't trip then you should test for power at the screw connections inside of the electrical panel.
Remove the screw that holds the dead front covering the breaker's connections.
Remove the dead front cover.

4
Test for power with your voltmeter set on AC volts on the highest scale.
For a single pole GFI breaker, touch the black lead from the tester to the silver screw on the GFI breaker and touch the red lead from the tester to the brass screw on the GFI breaker.
You should see 110 volts on the tester. If voltage is seen but the test button won't trip the breaker, then the breaker is bad and should be replaced.

5
Test for power on a two pole breaker by touching the red voltmeter lead to one of screws with a black or red wire connected to it.
Touch the black lead to the other screw with a black or red wire connected to it.
You should read 220 volts or close to it on your voltmeter.
If you read voltage and the test button won't trip, the breaker is bad and needs to be replaced.

What to do if the breaker won't reset and keeps tripping when turned on
6
Unplug everything that is plugged into any of the outlets on the circuit in question.
Try resetting the breaker again by pushing the switch all the way to the off position and then turning it back to the on position.
If it won't reset and trips when the breaker's switch hits the on position, it could be a bad breaker or a problem in the circuit itself.
7
Use your straight-tipped screwdriver to loosen the brass connection screw or screws on the GFI breaker.
Pull the black hot wire, or wires, out of the breaker's connectors.
Loosen the silver screw the white wire is connected to and remove it from the GFI breaker.

8
Push the switch all the way to the off position.
Turn the switch back to the on position.
If the breaker still won't reset, then the problem is the breaker itself and it should be replaced with a new one of the same size, brand and model.
If the breaker resets normally and the test button trips the breaker when pushed, the problem is in the circuit itself and an electrician should be called to find your ground fault.

9
Reconnect the black wire, or wires, to the brass screws on the GFI breaker.
Reconnect the white wire to the silver screw on the GFI breaker.

10
Replace the dead front cover into the breaker panel.
Install the screw or screws that hold the dead front in place.

Home fuse box breaker issue


Hi Rex,

It sounds as if the upstairs bathroom outlet and the outdoor outlet are on the same circuit. There's a very good chance that these are GFI or "ground fault interrupter" type outlets, as these locations (and others) have required this type of protection for over 30 years. It was a common practice to run a circuit from the panel to one of these locations (or another) and then run from here to the next outlet and then on to the next. Since the GFI outlet could be purchased for around $10 instead of $30 for a GFI breaker, electricians would install outlets instead - both offered the same protection. A "regular" breaker would supply power to this circuit - but the very first outlet would get a GFI type outlet. It would be wired to the LINE terminals and the cable that feeds the rest of the outlets on this circuit would be connected to the LOAD terminals. If there was a ground fault condition, this GFI outlet would trip, but the circuit breaker would remain on. You would locate and RESET the tripped GFI outlet to restore power. The only time the circuit breaker would trip is if the circuit was overloaded. Overloads would NOT cause the GFI outlet to trip.

Now that you understand how it was typically wired years ago (and still a lot of times today), you should check all the outlets outside your home, in bathrooms, basements, garages, and inside your home next to doorways that lead directly to grade of your lawn or deck. These are required places for GFI protection. Press the RESET on any tripped GFI outlet to restore power. If the outlet will not RESET, there is a condition where the hot wire (black, red or blue insulated wire) is in contact with ground, or a device or appliance connected to the circuit has a problem. Unplug anything connected to the circuit and attempt to RESET again. If still unable to reset, open the outdoor outlet again and carefully pull it out and away from the box. Inspected for damaged or crushed insulation and repair / tape as needed. Before reinstalling, try to reset again. If it holds, trip the GFI by pressing TEST button. The RESET button should pop out. Reinstall the outlet and make sure the wires are not crushed or cut. Press the RESET button again. If it trips, you will have to remove the outlet again and take more precautions against damage to the insulation. it is also possible that the GFI outlet itself has failed, in which case it should be replaced.

GFI circuit breakers and outlets are supposed to be tested monthly by simply pressing the TEST button and then the RESET button. Replace any GFI device that does not test correctly if wiring and devices / appliances connected are OK.

I hope this helps & good luck! Please rate my reply - thanks.

I HAVE A 3 PHASE 480V. 50 AMP TED134050 BREAKER WHICH FEEDS A 45 K.W. TRANSFORMER.WHICH TRIPS OCCASIONALLY, NOT OFTEN. IT RESETS O.K. WHAT DO YOU SUGGEST?


Hi,

I would get an amp metetr on it and see what the load is.... if it is running continually at over 40 amp. then you are overloading it...and need to shed some load...

If it is not then the breaker is going bad and needs to be replaced...

Our rain bird was off and i changed the battery. I tried to turn it on manually and it says, no ac?


The battery only holds the program in the memory. The No AC message tells you that the AC power that is supposed to operate the valves is not getting to the control unit. Someplace there is a power cord with a transformer that is taking the house current at 120V and powering the unit. Something has been disconnected or a circuit breaker is tripped. If there is an outside socket with a GFI in it, try resetting it.

Malibu Lighting Breaker Switch


There are two possible problems you could be facing (excluding the transformer going bad) If you have replaced light bulbs with higher wattage ones, you could be drawing too much current through the transformer. (It is common for MR-16 style lightbulbs to be 20w in landscape lights, but 50w for inside lights, and the local hardware store usually only carries the 50w replacement lamps) Each transformer has a specific amount of "watts" it can supply (anywhere from 100w to 1000w) If you exceed the supply wattage of the transformer, the breaker inside the transformer will trip. The quick and easy way to test this is to take a few of the lightbulbs out and see if the breaker will hold.
If you are positive that the total lamp wattage does not exceed the rating of the transformer the second possible problem (but less likely) is that you have a lamp socket or wire connection that is full of water. This water between the two conductors draws current just like a light bulb and can cause an overcurrent fault. This is usually more common if it starts to trip right after a heavy rain when the ground gets saturated with water.

Good Luck!

Unit comes on and runs for 5 minutes, the circuit trips off


30 is the correct size breaker for this unit. It sounds like there is a grounding issue going on in the system. Or off of the Thermostat. Something is grounding out causing the switch to trip. Are you running #10 wire to breaker and the unit? If not you will need to increase your wire size

Two 15 amp arc fault breakers installed on two adjacent circuits. One works fine - does not trip. The afi breaker beside it trips as soon as it is flipped on. We tried switching circuits, but both circuits...


It's possible that the first breaker that you said does not trip - it could be that breaker is failing to trip on a bad circuit. That is, it could be you have a bad circuit but that first breaker is not detecting it and pretends everything is OK. If your new breaker trips on the first breaker's circuit, the curcuit it probably bad and the breaker in not working properly. The most common problem for failed circuits is a stray ground wire in a box somewhere in the curcuit resting against a hot or neutral wire. You'll have to take apart every connection on that curcuit to find it. Not fun.

3-pole 60 Amp Circuit Breaker is tripped and won't reset.


When this breaker tripped, it did not go fully to off. Push the breaker all the way off and then all the way to on. It should be fine. If not manually push it to full off once again and then back on. If both attempts fail the breaker will have to be replaced. good luck.
