19 amp toaster oven

[rob12013]

Hello
I've always just followed prints so I have some basic questions
about a commercial big toaster oven 120v. Its name plate
says max fuse size 19 amp. Right now the plug has been rigged to
fit a 15 amp receptacle & other equipment is on this circuit so it trips

I'm looking to get a 25 amp GFCI breaker because of cord and plug
get twist lock 30 amp plug and receptacle
keep the new cord to 3 feet

There a existing 2 pole 30 amp plug not in use
need to pass inspection first time always
just got my workman?s comp to today I'm included

thanks
Rob

We almost always go by the name plate. I think 20 would be okay but definetly not 25.
Any time an appliance uses 50% or more of a circuit it is required to be dedicated. It probably tells you that in the instuctions.
But, if they we're kind enough to put a name plate listing on it. I would use that

Are you sure the nameplate says maximum of 19 amps? Does it say fuse? How was the plug rigged? Was the original replaced with a 5-15 or a 6-15 plug?

I'd investigate whether the oven can be converted to 208v or 240v.

Added: What is the oven's amp or power rating?

 

[Dennis Alwon]

Any time an appliance uses 50% or more of a circuit it is required to be dedicated.

I don't think this is an accurate statement. I believe you are making a reference to art. 210.23(A)(2). This is for equipment fastened in place in conjunction with lighting units, cord & plug equipment, etc.

You could have a 10 amp appliance and a 5 amp appliance and still have them on the same circuit. We see it often with Dishwasher and disposals on the same circuit.

Now I will assume the op has a cord & plug appliance in which case 210.23(A)(1) may apply

210.23(A) (1) Cord-and-Plug-Connected Equipment Not Fastened in Place. The rating of any one cord-and-plug-connected utilization equipment not fastened in place shall not exceed 80 percent of the branch-circuit ampere rating.

Thus you cannot install a 19 amp unit on a 20 amp branch circuit.

I question the 19 amp bit.

Hello
I looked at the oven here's a picture just wondering if
with continuous load maybe should be on a 25 amp breaker
also it does need to be on a gfci correct? for cord and plug
it's a ben and jerrys
thank you
Rob

It says it runs on 120 volts and draws 19 amps. I see nothing saying fuse or breaker.

The appliance will not determine whether or not GFCI protection is needed. If the receptacle is 15 or 20 amps, 120 volts, and installed in a non-dwelling unit kitchen, it must be GFCI protected.

Is the original cord plug gone?

 

[rob12013]

yes I think the cord was replaced with 12/3 because on the name plate it
says wire 14/3 and it's about 7' long. I called the tech at the place the makes these he said there is a motor in there also. he also said 20 amp breaker would trip. is it crazy to think i need a 25 amp gfci breaker there around $50.00.
thanks

 

[iwire]

14/3 cord and a 20 amp circuit is what I would provide.

 

[neutral]

The mfg. info says 120v 16 amps. Whoever stamped the plate had the number die upside down? or maybe had a liquid lunch before doing his/her job.
In the pic posted it also has 14-3 as the wire size?
The mfg. also list this as the cord cap to use. 120 Volt, 20 Amp
(NEMA 5-20 P)

Charlie.

I would reinstall factory cord and plug. If it trips then something is wrong. 14 sj will be fine with 16 amps. Put in 20 amp breaker either gfci or receptacle with gfi.
Your trying to fix something that is not broke.

 

[rob12013]

your very right I'm just going to print out the cut sheets on the unit to show the inspector
thank guys a big help

 

[Npstewart]

Thought you have to use a #12 wire for a 20A circuit in commercial...240.4(5) ??? Correct me if im wrong... The manuf. should have made that piece 240v in my opinion

 

[Dennis Alwon]

I agree with Charlie. If you go to Nu-Vu.com and look it up this is what you will find.

SPECIFICATIONS:
ELECTRICAL:
• 120/1 at 16.5 Amps.

Yet the table states 14.5 amp draw for 120v.

I would not use 14/3.

Look at table 400.5(A) column B.

It would be a code violation to supply a unit equipped with a 20 amp plug at 25 amps.

The 'motor' in this will be fractional HP and will not trip a 20 amp breaker.

 

[Dennis Alwon]

Look at table 400.5(A) column B.

Sorry I was thinking the branch circuit-- should have realized it with the 14/2 instead of 14/2. :grin::roll:
