News flash: The name plate on the oven states "four wire". Since the two NM-B cables can easily replaced, change them to NM-B 3#8 and replace both breakers in the subpanel to 40 AMP. It is rated for 50amps according to my chart so the breaker in the main panel should be changed to a 50AMP. I would try utilizing the #6AL XHHW since changing it out would be difficult. If it's not a ground but actually a neutral, where are the grounds? You will need to ground everything. My first concern looking at the subpanel is if that bare #6AL is in fact a ground and the two appliances are straight 240V then the two white wires connect to the buss should have some green tape on them. Kitchenaid nameplate indicates 10.8 kw v:
#40 amp circuit breaker series
The oven/microwave combo is a Bosch Series 800 (HBL8752UC). The cooktop is a Kitchenaid downdraft (KCED606GBL). I have attached additional photos of the 3-6 cable below. The main panel is on the opposite side of the house. The subpanel is in the basement immediately below the kitchen floor underneath the wall oven. I should also add that I plan to hire an electrician to do the work, but would like to know what to expect and, if possible, run some of the wiring beforehand to reduce the labor cost.Īt the main panel the aluminum strand attached to the bus bar in the subpanel is attached to the bus bar in the main: I have attached a couple of photos of the wiring and subpanel. The insulation for the 3-6 is grey plastic/vinyl. The subpanel could be physically removed. Replacing the 3-6 wiring would be much more difficult, as it is routed behind walls and over drywall cielings. In response to the questions, the NM-B wiring can be easily replaced from the subpanel to the oven and cooktop. As both the new cooktop and wall oven each require 40 amps, what is the best way to proceed? Is the single 40 amp breaker in the main panel and the 3-6 wiring to the subpanel sufficent to meet the load demands of the new 40 amp units? The subpanel currently has one 30 amp breaker feeding NM-B 10-3 to the cooktop and one 30 amp breaker feeding NM-B 10-3 to the oven.
We have a 200 amp main panel with one 40 amp breaker for the oven/cooktop that feeds 600 volt 3-6 aluminum wiring to a subpanel. The old units were rated for 30 amps each and the new units require 40 amps. We are upgrading our wall oven and cooktop.
