I have a situation very similar to using two oven in one outlet. I'd like to install a 30 amp GE Advantium 220v oven and a 20 amp GE thermal oven on an existing circuit with a 50 amp breaker. However, both installation manuals ask for dedicated circuits. Quoting the Advantium manual here: "Power should be supplied from a separate, dedicated 30-ampere branch circuit."
Ordinarily I'm a follow-the-instructions kind of guy, but I did notice that the manual used the word "should" in this sentence rather than the "must"s which were liberally sprinkled elsewhere. Pulling a new circuit is possible but a lot of work. I'd appreciate feedback from experienced DIYers or electricians. If I follow my instincts and install both ovens to the existing junction box with the existing 50 amp circuit, what risks am I taking?
