convection oven wiring
 

I bought a convection oven (Bosch, 700 series), and the installation
instructions say it need 15.8 amps (120/240V).
Every book and documentation I researched are mentioning electrical
ovens needing 40 or 50 Amps, so I am a little surprised, and would like
to hear from anybody whether maybe newer ovens are drawing less
electricity ?
I was thinking going for a 30Amps breakers (I don't even think I can
find find 20 Amps 2 poles breakers for my service panel).

thanks.

Fred.

Hi,
15.8 Amps at what voltage? At 120 or 240?

Every book and documentation I researched are mentioning electrical
ovens needing 40 or 50 Amps, so I am a little surprised, and would like
to hear from anybody whether maybe newer ovens are drawing less
electricity ?
I was thinking going for a 30Amps breakers (I don't even think I can

thanks.

Double check the nameplate on the oven to confirm, but it is not unusual for
convection ovens to require less power. Do not install a larger circuit
breaker than is required for your unit. In this case a two pole 20 amp CB
is sufficient. If you want to install a larger wire for possible future
upgrades that would be okay, but stick with the proper circuit breaker and
receptacle.

Convection ovens typically draw a lot less power than the traditional
type, so this isn't much of a surprise. Rather than consulting books
which provide general information, you need to go with the specific
information provided by the manufacturer of your oven -- this would be
true even if you were installing one of the big 40A or 50A units -- and
that specific information seems to indicate a much lower amperage.

I was thinking going for a 30Amps breakers

Not necessary -- and if the oven is cord-and-plug connected, instead of
being permanently wired in, it's a violation of the electrical code,
too. (A cord-and-plug connected 15.8 amp device certainly has a 20A plug
on it. Code doesn't permit installing 20A receptacles on a 30A circuit.)

(I don't even think I can
find find 20 Amps 2 poles breakers for my service panel).

I bet you can. Have you checked? They're pretty common.

thanks everybody for your comments. to answer some of your questions,
and summarize:

- I posted twice, because I inadvertently clicked twice :-(. sorry
- I thought bigger was better, but didn't know.... I'll follow your
advice, and get a 20 Amps breaker (my mistake, they do exist).
- it's not a cord and plug oven, you need to do the connection
- I'll check the price of the wire (#10 is really expensive...), see
how much I save if I go with a #12.

thanks a lot ! I'm glad I asked.

Hey, no problem. Happens a lot.

Bigger isn't always better. Sometimes it's worse (e.g. if you need a 20A
receptacle, you can't use a 30A circuit). Usually, it's just unnecessary.

- it's not a cord and plug oven, you need to do the connection

In that case, a 30A circuit is permitted by Code. But it's not necessary.

- I'll check the price of the wire (#10 is really expensive...), see

Lots -- which is a pretty good argument for going with the 20A breaker.

thanks a lot ! I'm glad I asked.

Good luck!

Check your specs. The bosch website seems to list the 700 series ovens
as follows


Broiler Element Wattage 3500
Convection Element Wattage 2500
Bottom Element Wattage 3000
208-240V/60Hz, 4-Wire Check mark
Amps 20

depending on what model you have.

So its a 240 V circuit you need , but only 20 amps
