Question about Hobart AM14-253 Free-standing Dishwasher

1 Answer

Verifying breaker rating of AM-14

I'll be supervising the electrical installation of an AM-14 unit purchased at an auction, and want to clarify the manual's recommended wire sizing. The motor nameplate states 200-230 volts and the voltage selector block at the motor is correctly connected. It also has the electric heat option. Just curious as to why we need 50 amps capacity. I can't read the full-load current on the motor's nameplate, but if I assume it's less than 10 amps, do the electric heaters draw that much additional current? I didn't see anywhere in the literature where these heater wattage is given.
Thanks......Lee

Commercial dishwashers don't take it for granted that the hot water is hot enough to sanitize. And, they know restaurants need to turn dishes.

So there is enough heat to make sure warm water heats up quickly to sanitizing temperatures.

I had a house inspection and in the main panel I have a 20 amp QT breaker that is rated from 15-35. I have a 20 gauge wire and and a 15 gauge wire running to this breaker. Inspector says I need a 15


He is correct. I'll not go into the particulars but the fact is, you have two separate circuits connected to the same breaker. Separate the two circuits by installing another 15-Amp breaker. Although I understand your situation, please understand wire gauge and electrical amperage are two different animals. Breakers are rated in Amperage and electrical conductors are sized by wire gauge. That said, the 20 gauge wire you speak of is actually a 12 gauge conductor and the 15 gauge wire as you say is a 14 gauge conductor. Have a good day.

Installation: Electrical Requirements


13Mb product manual is a big download ... electrical info page 13:
http://waterheatertimer.org/pdf/AO-Smith-Cyclone-gas-water-heater.pdf
http://waterheatertimer.org/pdf/AO-Smith-Cyclone-electrical-connection.pdf
Recommended both water heaters require dedicated single-phase 15 amp 120Volt line with correct polarity. This is 14 gauge wire and 15 amp breaker for each unit.
I would put both water heaters on surge protection and GFCI. Most water heaters are not protected from surge, and manual says line noise can affect operation of water heater.
Your local code would say if GFCI is required. Install GFCI breaker in main panel if required.
Install inline surge protector: Or add main breaker box protection.

How do i install a 14-3 wire with ground to the breaker


Following wiring diagram is for general purpose household 120V-240Volt service.

http://waterheatertimer.org/See-inside-main-breaker-box.html
http://waterheatertimer.org/Color-codewire.html

Why are you asking that question without saying what you are wiring? 120Volt, 277V, 480V etc?
What does rating plate say on device you are connected to 14-3 wire?
And what amp/volt/watt rating are you connecting to 14 gauge wire?
No electrician would omit that information.
14-3 wire is usually only for 3-way switches and other light duty applications.
Must be connected to 15 amp breaker and no larger.

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.

Purchased "Reliance Lowboy electric water heater"


The water heater has two 4500 watt elements.
However both elements are not turned-ON at same time
So the water heater is 4500 Watts

Volts x Amps = watts
Amps =watts divided by volts
Amps = 4500 Watts divided by 240 Volts
Amps= 18.75

So that says a 20 amp breaker ... except for the 80% rule
80% rules says for safety, your Amp rating should be multiplied by 80%

20 amp breaker X 80% = 16 amps
20 amp breaker is actually safe for just 16 amps, and your water heater draws 18.75 amps.

The calculation shows you need a 30 Amp breaker.
30 Amp breaker requires 10 gauge wire.

I have an Electric Furnace rated at 45 Amps/240v. Would a 45 amp breaker suffice for this unit?


Most likely not.Heating equipment circuit breakers have to be calculated at 100% of the load continuous. That would mean the circuit breaker would have to be rated at 45amps continuous. Most breakers are not. Most breakers are rated at 80% of their rating for continuous loads. So if you installed a 60 amp circuit, 80% of 60 = 48 amps. This would fit your requirement. That would be a 60amp breaker, with #6 cu conductors.

Remington electric tiller circuit breaker goes off


For about $20.00 you can buy 50 feet of 12 guage 3 wire yellow extention cord. You will then get all the amps you need to run your unit. If it still fails, you have a problem inside the tiller.

Really sounds like a power problem. Start by turning the breaker off and then back on. I have seen breakers trip but the handle does not move. This can drive you nuts as it "Looks" like the breaker is o.k. If this does not help, then you have to start by verifying that you have the correct voltage to the unit. If you do, the problem is anywhere from the plug/ cord, to anything inside the unit. This requires following the circuit one item at a time.
If you don't have the correct power, you need to address that.

Good luck and hope this helps.

WITHOUT ANYTHING TO LOOK AT I WOULD SAY HE CONNECTED HALF THE LOAD TO ONE OF THE PHASE WIRES AND THE OTHER TO THE OTHER PHASE WIRES , PHASE WIRES MEANING 120/240 SINGLE PHASE , SO IF THAT IS THE CASE TAKE THE WIRES HE HAS BUNDLED TO ONE PHASE OR ONE TERMINAL ON THE BREAKER AND THE OTHER TO THE OTHER TERMINAL OF THE BREAKER IN SOME CASES IT IS NECESSARY TO CONNECT THE WIRES WITH CONNECTOR, APPROVED TYPE AND THEN TO THE BREAKER TERMINAL ,THIS JUMPER SHOULD BE RATED THE RATEDING OF THE BREAKER YOU ARE INSTALLING ,GOOD LUCK
