Kitchen Electrical Outlet

In the entire camper there are exactly two electrical outlet circuits. How they are divided is a mystery to me. All that I know is that running a blow drier in the bathroom while using the microwave is not an option... Since the new tankless water heater didn't have a 120V option like the original one did, I was left with an unused 15A breaker and a set of AC power lines under the kitchen cabinets. Since the only other outlet in the kitchen is next to the entry door and any counter top appliances I use can barely reach it, I decided to add an outlet in the kitchen. The best place to put it was directly under the counter top between the oven and sink. With this placement, I can set a toaster or crock pot on the covered stove top or on top of one of the sink lids. Also, since the only thing on the breaker is this one outlet, I don't have to worry about it tripping because my wife want's to blow dry her hair!

In case you were wondering:
Ground Wire (Green or Pure Copper) connects to the little screw floating by one of the corners.
Neutral (White Wire) goes to the silver terminal - should be the longer of the two outlet slots.
Hot (Black Wire) goes to the gold terminal - should be the shorter of the two outlet slots.

This was definitely the best place for the outlet. I removed the drawer under the sink and measured where the outlet should be.

I didn't use an outlet box because it was unreasonable. This isn't drywall, so cutting a nice square wouldn't have been easy. Also, the wood here is about 1.5 inches thick so the back of the outlet doesn't stick out at all, and it is only an inch under the counter top. I did cover the back of the hole with electrical tape to prevent anything from somehow sneaking in there.

I made an initial hole with a drill and then used a jig-saw to cut the rest away. It isn't the prettiest, but it's a perfect fit for the outlet.

With the breaker fired up, the outlet tests out OK. A six outlet adapter fits perfectly in the space under the counter top. You might think it was installed upside down, but this is to prevent anything from falling across the two terminals and shorting the plug. An object would first hit the ground pin, potentially preventing a short between the hot and neutral lines.
