Power Inlet Box Installation
Excellent product which did meet the local electrical code requiring a weather tight box and upward sloping plug in method features (rectangular boxes with spring loaded covers do not meet our local codes). However, the box did not come with an installed grounding lug, or a threaded hole designed for a pigtail ground.

I would assume that if continuous metal conduit is used to connect to the transfer switch and load center, a separate grounding connection to the box might not be required.... more

Well Built And A Great Value
This was a super simple installation with a well built box, and a great value, but a I did have a couple small concerns...

1. To use the most logical knock out on the back of the unit (at least for the clamps that I had on hand) you will need to put the clamp in on the inside and use a small spacer washer inside in order for the box to sit flush to the wall. It's not a big deal really, but odd design in my opinion.

2. This probably won't matter to most, but the opening in the bottom... more

Midwest Inlet Box
I do not understand why this item is discontinued, it is a very good product and easy to work with. The angle of the plug connector is good. The cover, which will close on the connector and can be locked, is also good.

Mariano,
Sometimes a manufacturer will discontinue a product because they have introduced a new part number or a new supplier; or made other improvements.

Installation of the box was easy. The side and bottom knockouts give additional water entry prevention and the lock hasp provides security.

One concern is that the bottom opening that allows power cord to be connected and secured. When not in use, it can provide a home for bees or other insects. Prevent this by placing tape over bottom opening when not in use. Maybe this is why this item has been discontinued?

Good Product. Lid Issues However
The box is made the same as most breaker boxes- tough, heavy duty metal. There are several punch-out holes to choose from.

The only issue is the lid does not completely close off the compartment when closed. I suppose they left this so the generator cord could stick out. If so, that's OK, but when no cord is attached it should completely closed off so wasps and spiders can't make it home.

I modified mine with a piece of metal attached to the bottom to prevent insects from using it. I... more

Big Enough To Be Easy To Work With.
Nice external hookup box. Easy to mount and easy to wire. Lots of room to bend the wires.

I like that I could lock the box with the cord inside so it won't get lost.

Very Nice
This product makes the most sense in how it's set up. The connection is covered and the cord isn't bent at a right angle. Lots of space to make the connections.

If nothing else, sort the reviews from lowest to highest. There aren't any low reviews!

Electrician Review
This is a well made inlet box. It has room for wire and an easy pre-wired ground terminal. Should last for decades.

30 Amp Inlet Box Easy To Install - Knockout Near Bottom Of Box
This Midwest Electric 30 amp inlet box worked out beautifully.

At first I thought it was the maybe too large and the wrong shape for my house because I was installing it from a crawl space. As it turns out the electrical knockout was near the BOTTOM of the box, so I was able to drill a hole just above the sill plate and mount the box vertically near the bottom of my cedar tongue-in-groove siding. It's a very good design. The Twist Lock Connector fit was perfect too.

Never Again
The Halloween snow storm was my 2nd time with losing power for 5 days. I will never again go without power again. Freezing, eating out, throwing out everything in frig and just the whole inconvenience of it. I purchased a Honeywell 6500 generator and had my house wired. This was the best insurance I have in case it happens again. I am very pleased with the generator and the price was great and delivery was right on time.
