    If it trips instantly every time, you must have something shorted out. I know those things require 2 sets of power, like 2 /50 amp breakers, One of the things that stopped me from hooking one up. I don't think it is the breaker. It is 220 volt, 2 wires from each breaker, big wires, like 6 or 8 gauge, 50 amp, then the ground. Hope this helps.

    It runs for about 5 to ten minutes then trips. I used the orignal wires from the existing hot water heater. It had a four set breaker that was 15/25/25/15 I repalced it with a 25/30/30/25 and it is still tripping after about 5 to 10 minutes.

    I am in texas there are two wires that come out out the unit I used the existing wires from the breaker box that was connected to a hot water tank. It is 220 volt and the unit draws 48 amps at peak. It is grounded from the existing ground wire from the previous tank

You had an instant heater there before? Or a different type? Your breaker numbers don't mean anything to me, I need amps and volts, what is the amp? 30? and the volt is 220? Or are you in Europe?. And you had the four wires in there before? And you have all 4 wires on the heater line? And the heater is grounded? It should work. Unless it is not getting enough juice, but you already upped the amp. Let me know what you got.

    The only thing I can think would be the breaker is no good, but you said you changed it out and it did the same thing. So we can rule out the breaker, but we can look at the draw of power and see if it is too much. If you can feel those wires right before it trips, see if they are warm or hot. The insulation. Unless you have a single wire volt meter that tells what the draw is. Also, what size is the wire?
    I was going to hook one of those up here at the house and they called for two breakers at 50 amps each, I don't have a space in my box for another double pole breaker. So I just replaced the gas heater.
    Now getting back to your box, do you have another breaker in there, like the air handler or compressor, or the range? That you can borrow for a minute? Just swap the wire to it and see what happens. gotta narrow this down some how. Check it out.

According to this table that shows all Titan water heaters technical specifications, your Titan N100 draws 49Amps. This other table tells you what breaker and wire size to use for your Titan installation. According to it, the N-100 uses wire 6 AWG which can handle high current. If you are using a smaller cable, like the one tanked water heater use, your cable is going to get hot and tripper the breaker.

Hatco booster blowing breakers


Copy following link:
http://waterheatertimer.org/Water-heater-is-blowing-breaker.html

Hatco booster heater typically has 2 sets of thermostats and elements located on each end of heater.
Both sides might be controlled by same 60 amp breaker, or the heater might be controlled by two separate 30 amp breakers.
Be sure you have correct wire and breaker.

After reading steps on link above, add comment and say if this is new installation, or older installation that suddenly started throwing breaker.

Bosch AE-9.5 keeps tripping the reset


All resets and breakers trip with high heat.
Do you mean the tankless unit is tripping the 40 amp circuit breaker?
Or the thermal cut-out, located on unit, is tripping?

Is this a new installation?
Or was the tankless working before and stop working?

Copy following link to check wiring.
AE 9.5 requires 40 amp breaker and 6 gauge wire.
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html

If the unit is tripping the thermal cut, -out, then product manual says to call Bosch or service technician.
Call Bosch 866-330-2729
http://waterheatertimer.org/pdf/Bosch-Powerstar-AE3.4-7.2-9.5.pdf
Thermal cut-out can trip if water flow is too low.
Try changing power selector screw from Hi to Lo so only 1 element is ON. See diagram page 6 of manual.
Adjust the 'outlet service valve:' The manual recommends that a ball valve be installed between hot outlet and faucet. Adjust the valve so more water flows to faucet.
Remove aerator, clean aerator, don't use low flow restrictions or low flow shower heads, replace leaky faucet cartridge on single-handle faucet.

What size wire and how does it hook to thr unit rpkb-036jaz


Look at rating plate on side of unit for Volts, Amps, Watts.
Volts x amps = watts.
If unit is 240Volts, then you need double-pole 240Volt breaker
If unit is 8500 watts at max power, then 8500 watts divided by 240Volts = 35 amps.

What size breaker for 35 amps?
When electricians figure load rating for breakers, they use the 80% rule.
40 amp breaker x 80% = 32 amp safe maximum load for 40 amp breaker. Use 8 gauge wire with 40 amp breaker.
50 amp breaker x 80% = 40 amp safe maximum for 50 amp breaker. I use 6 gauge wire with 50 amp breaker.
60 amp breaker x 80% = 48 amp safe maximum for 60 amp breaker. Again, use 6 gauge wire with 60 amp breaker.

How to connect wires to unit.
First of all, all outdoor HVAC units require power cut off located next to unit.
This lets the mechanic, or service tech turn power off to work on unit, even if the mechanic does not have access to main breaker box.

Next, open unit to see where wires connect.
If unit has wires, then connect both hot wires from 240 breaker to the wires inside unit. Connect bare ground wire to green ground screw.
If unit has terminals. The terminals will be labeled L1 L2. Connect each hot wire from 240Volt breaker to either one of the screw terminals. Then bare ground goes to green ground screw.

Copy following links for basic illustrations connecting wires to terminals, and to breakers, and selecting wire size.

Thermostat sticking titan n180


The thermostat is there to protect the water heater. I don't think it can overheat and make the breaker trip. If you tried to reset the unit and it's still not working, you should send your Titan N180 back to the manufacturer to be repaired. The 10 year warranty if against leaks. You have 1 warranty in your Titan components.

Breaker is tripping off every 20 min i know amp are right plz adviced me how to fix


need to know which breaker- house ele. panel breaker, which should be a min. of 50 amps,or the element breaker located inside either the upper or lower cover. If it is the element breaker/reset switch, this can be changed with great ease. Turn the power off and the ele. panel, check with a voltage meter to make certain power is off at the unit, loosen or remove the wires- making sure as to location of wiring, remove the switch and replace, reconnect wires, turn breaker back on,and you should be ready to go, This is assuming you have a 50 amp breaker in the electricial panel.
