3Phase 60hz 5 Wire Oven

y0manda

From California,
I went out to take a look at a previous customer of mine that needed help installing a Revent Oven. the oven requires a 3phase 60hz 220V 5wire electrical connection. They are commercially zoned but only have two leads and a ground going into the weather head in the main service panel. Is this oven possible to hook up with their current set up? Thanks in advance.

What does it draw???

This CANNOT be done unless they have a phase converter installed. Depending on what the oven draws and what size service they have will determine how feasible this is.

WHY did they buy a piece of 3-phase equipment without first confirming they had 3-phase service with the capacity to handle it ???

Don't tell me, they got a bargain. Right?
Well that just went out the window.

called Revent this morning, It must have a 3 phase panel to power it. Called the power company and they only have 1 phase going to property. They spent 20+k on the oven.
Also they purchased a dough mixer that is a 3 phase and I think it was about 10k. They have a tortilla machine and I wanted to check the specs for that but it was still wraped up and I didn't want to mess with it since it's not my business. These people have serious issues.

The phase converter is not a good idea. The best thing to do here is for the consumer to return the oven and buy a single phase oven.


what is the kw rating?

well since you've said all that.... this customer better get in touch with poco and see about them bringing 3-phase to the building. some lucky electrician is going to have a nice pay day.

specs on oven.

They currently have a 400 Amp single phase surface mount service panel.
There are probably 4 sub panels within the store.
What would a qualified electrician charge for upgrading the service panel to a 3 phase and how many amps would you recommend?

Speedy Petey

I never said it was a good idea, in fact I don't think it is either. That is why I questioned whether it was even feasible.

Yup, yup!

What sort of moron drops 10's of thousands of dollars on kitchen equipment like that, without even being sure it can be accommodated? I guess this is a case of "you don't know what you don't know". They were probably truly clueless. It's all electricity, right?

What's the problem?
Everybody goes through
"phases" right?

That shows that it's a gas oven.

No need to worry about kilowatt ratings with a gas oven.

You do, however, need an Electrical hookup for the igniter!

But these ovens come either way. G or E.

That three phase 120 volt oven receptacle is going to be hard to find.

It's hardwired.

y0manda

I did all the electricity in the new bakery, also the framing, gas, tile, water, Drywall, FRP, Installed a 2,000+lb range hood, built the exhaust vent for the grease trap, and the make-up air fan/ducting. had the ansul system installed and filled the tanks. Even the plans called for 4 220v outlets in the bakery. So when I come to look at the oven to install I was shocked. He still owes me 8k and wont pay untill he gets the ok from the Health Department. Never knew that was part of the conditions. oh yeah. when I first went to look at the job, he showed me where the previous contractors that bailed out dug a hole and I can "tie" into for drains. LOL I should of known better, I ended up connecting the drain 90' away and cutting 30' of concrete and digging 5'.deep at the main. I didn't even charge him extra for that because my contract read I will do any necessary plumbing to connect floor drain and sink...... My mistake I learned from. OH WELL I am finished and want my fkn money

Magnettica

How can it be hardwired? It needs some sort of means of disconnect unless the circuit breaker is within sight.

Is the circuit breaker within sight?
