| Hello all,
I have a situation that I need to figure our how to handle. I'm installing a wall oven. It's a convection oven rated for a 20amp breaker. It has a whip about 4 or 5 ft long -plenty to reach the junction box. Here's the problem. What's mounted in the wall is a single deep plastic box. I'd really prefer to have a surface-mounted metal box, but can I make this work (legally and safely) using the plastic box? Thanks! |

| Put a 20A receptacle in and a plug on the oven cord? Use the recessed box to junction to a short piece of cable to reach your surface mount box placed adjacent? |
|
| Thanks for the suggestions. I thought it had to be hardwired? Do I need to worry about heat from the oven and the plastic box? |

| Just hardwire it to the existing box. There is no problem using in wall plastic boxes. |

| Joed, Do "they" make a cover with a punch-out to run the whip wires through? What connector would I use? An MC squeeze connector? |

| "Do "they" make a cover with a punch-out to run the whip wires through? What connector would I use? An MC squeeze connector?" Blank covers with a knockout are available. The connector is whatever type of conduit the whip is made from. If the cable is large you may need to find an electric supply house (not a big box store). |

| I second abnorm's suggestion. |

| Thanks everyone! I like the extension box idea, but in it's current location I'm not sure it would clear the oven. There is about an inch overlap between the box location and top of the oven (the convection fan part I think). There is room to use the existing box, so I'll probably just do that. Just to be sure - no worries about the oven's heat and the plastic box?? The whip looks like MC (three insulated wires and bare ground) thugh I doubt that it is truly MC, so I'll go with the squeeze connector. |

| "Just to be sure - no worries about the oven's heat and the plastic box?? " Unless the installation instructions require metal, plastic is fine. Most residential ovens are 'zero clearance' to combustibles. |
