The Ultimate FAQ Guide to Recessed Electrical Enclosures

Why are recessed electrical enclosures useful?

Probably the biggest advantage of recessed electrical enclosures is that it is hidden, so it does not protrude from the wall, for example.

This leads to the space feeling less cluttered, more aesthetic and functional.

As a result, such enclosures are perfect for residential and commercial settings, as well as industrial ones.

Recessed wall electrical enclosure

Another advantage is that only one side of the enclosure has to be very protected, while the other ones can be more simple.

This is because a recessed enclosure is surrounded by something from all sides except one, so only that side will be exposed to the elements.

Recessed enclosures are perfect for distribution boards, different metering boxes, heating devices, measuring gauges, and any other such electrical unit.

What are some types of recessed electrical enclosures?

The two main types recessed electrical enclosures can be divided into are those that are upright and those that are laying down.

Upright recessed enclosures can be opened by pulling the door forward, either right or left, or out.

They are the typical enclosures that are versatile anywhere and for anything.

Recessed enclosures that are laying down can be opened by pulling the door up.

Recessed enclosure that opens up

Such enclosures are buried in the ground or installed into the floor.

This is useful for outdoor enclosures and residential enclosures installed in a home’s basement.

What can electrical enclosures be recessed into?

Recessed electrical enclosures can be installed into drywall, concrete, stucco, fire-rated walls, ground, ceilings, and roofs.

The walls can have tiles and other decorative elements – the enclosure will not be compromised or disrupt these.

All these materials, such as drywall, will protect the enclosure.

Except for the ground or soil.

 Enclosure recessed in soil

Water can seep through it and it can be basic or acidic.

If this is the case, then it is better to use 316 steel for the enclosure since this material is resistant to acidic corrosion.

What materials are recessed enclosures made of?

KDM manufactures recessed electrical enclosures from stainless steel, galvanized steel, and acier au carbone.

Sometimes, such enclosures can also be made with cold rolled steel and plastic.

Stainless steel is good all-around, being corrosion-resistant, strong, and not too heavy.

We offer steel in grades 316, 316L, and 304.

Steel grade 304 is the most common one to use in enclosures.

It is resistant to rust and is affordable.

Steel grade 316 has molybdenum in it, making it resistant to chlorine and saline water.

Enclosures made from this material are great for marine environments with salt or chlorine spray, such as recessing them near a beach or pool.

 Different textures of steel

Steel grade 316L has a very low content of carbon, which makes it stronger than 316 steel.

Galvanized steel is steel that is coated with zinc, making it resistant to rust.

However, this steel is heavy and expensive.

Carbon steel, also known as mild steel, tends to be cheaper than other types of steel.

However, it is also not very resistant to corrosion and can be bent easier.

Carbon steel is enough for recessed residential enclosures, though.

Cold rolled steel is steel that is further processed with cold temperature and rolls that condense the material, making it stronger and more dense.

Because of this, it is great for enclosures.

Plastic is another option. Normally, plastic enclosures are not great, but if they are recessed, then it could work better.

Plastic, especially ABS and polycarbonate are resistant to corrosion and impact.

Plastic recessed enclosure

Plus, you can request a polycarbonate window or cover that lets you look into the recessed enclosure and the electrical components housed there.

Plastic covers are popular with mobile home construction and other residential applications.

Does the size of the electrical enclosure matter?

Recessed enclosures can be divided into hand access size and personal access size depending on how big the electrical components are.

Hand access enclosures range from 36 inches squared to 144 inches squared in volume.

These enclosures are not that big, so they are used in residential and some commercial applications.

Personal access enclosures start at 18 inches in height and up to 36 inches, which is equivalent to 0.45-1 meter and above.

Of course, these are better suited for industrial or outdoor applications.

Do recessed enclosures have to be thin?

If you are mounting your enclosures into the wall, then you are limited to the wall’s thickness unless you are fine with it sticking out.

However, if the enclosure is recessed into the floor, then you are not limited as much to its dimensions.

What types of enclosures can be recessed?

Recessed electrical enclosures are the same as other enclosures we make in terms of shapes.

Namely, we offer free-standing and floor-mounted recessed enclosures, wall-mounted enclosures, and custom electrical enclosures.

Free-standing enclosures are perfect for large electrical units and instruments that are too heavy to be wall-mounted.

They could be of any height and width and are great for industrial applications.

Recessed free-standing enclosure

Floor-mounted enclosures are connected to the floor, so they aren’t portable.

Otherwise, they are very similar to free-standing enclosures in that they often house heavy contents.

Wall-mounted enclosures use mounting brackets, screws, and pads, but not as much when they are recessed.

They are perfect for smaller devices in residential and commercial sectors, and thus are cost-effective.

Recessed wall-mounted enclosure

Custom recessed enclosures can be any shape that you need, so you are not limited by preset designs.

Plus, different options for doors, including single, double, and multiple doors.

Single doors are perfect for smaller and less complex electrical units, whereas double doors are used for large and complicated units.

Multiple doors are used for huge industrial applications or for increased security.

What features can I request with recessed enclosures?

You can request windows, vents, hinges, sun shields, rain caps, locks, and knockouts or valves for outside cables.

Windows, as mentioned above, help personnel look into the enclosure and check the electrical components without having to open the door or cover.

    Enclosure with window

Contrary to what most people think, recessed enclosures can have vents, both as openings and fans.

It may be harder for these vents to operate because there is no helping breeze, but as long as they keep about 50 degrees Celsius inside the enclosure, everything is alright.

Vents help cool the enclosure down when electrical wiring gives off excess heat as it works.

Vents also help with regulating air pressure inside the enclosure, and lead away or filter out various fumes and gases that may impair the work of electrical components.

Regulating pressure is important because it also prevents condensation, which recessed enclosures may be more vulnerable to since they are partially inside, but also outside.

Recessed enclosure with vents on the back and front

Hinges and handles facilitate the opening of the door or cover for easy access and maintenance.

Sun shields are basically another layer on top of an enclosure that reflect solar radiation, controlling inner temperature of the enclosure to prolong the life of its electrical components.

Usually, sun shields are on the top panels of enclosures, but with recessed ones, the sun shield should be on its front panel.

Except, if you have floor-recessed enclosures, in which case the sun shield should be on the top. Basically, wherever the door is.

Rain caps in recessed enclosures are basically protruding top panels that shield the rest of the door, as well as any locks and windows, from rain and snow.

Such accessories are not really possible with enclosures that are recessed into the ground or floor.

  Rain cap

Locks secure your electrical components against tampering or accidental operation.

Knockouts and valves provide a way for cables and wires to enter or exit the enclosure.

You can request knockouts on any panel, including the top and the back panels.

Valves will better protect the electrical components from any dust or moisture since they are basically gaskets.

 Valve for cables and outlets

However, knockouts are easier to make, and they may be enough for your needs.

All these accessories are useful for recessed enclosures to optimize their purpose.

What is an over the box?

An over box is a cover for a damaged recessed meter box.

However, they can also be used if you want to replace and upgrade the existing covers you have.

Overboxes are the outside part of a recessed enclosure, which includes a frame and a door or cover.

Note: recessed enclosures and over boxes are also referred to as access doors.

 Overbox

What are some options of the recessed enclosure’s cover?

The cover, also called the overbox, can be opaque, have a window, or function as a door.

As mentioned above, windows provide a way to look inside the enclosure and check up on gauges and other electrical components without having to open it.

Windows can be clear, but they also can have a dark hue that protects the wiring inside from harmful UV rays.

Hinges covers also facilitate maintenance.

It can also have flush cover or a simple box.

Now, flush covers have an outer frame.

Thus, when they are installed, they are snug against the wall, invisible from the side.

Flush recessed enclosure 

Recessed electrical enclosures with protruding frames can look good, but they will not be invisible against the wall or floor.

Yet, these frames make installation a little easier because the frame serves as a guide.

Simple boxes do not have such an outer frame, so when they are installed, they are invisible from the side.

This can be good in terms of aesthetics but can be a little more difficult to install.

How are recessed enclosures installed?

Usually, the process is simple.

A hole is cut in the wall or floor or ground and then one of two things happen.

If the electrical components require extra protection or are placed in the ground, then the full enclosure is installed into the hole.

If the drywall or concrete is enough protection, such as for residential electrical components, then the hole is left alone.

If the wall or floor is made from stucco or plaster, metal lath is needed as well.

In both cases, the frame could be mounted after, and the cover or door is installed as well.

  Mounting a recessed enclosure

Plus, if there are cables running from the enclosure to an outside source, these are pulled through the valves or openings.

The same applies to any outlets housed in the enclosure.

You can also install the enclosure a little deeper, so its surface is behind the surface of the wall or floor.

This allows you to place tiles, bricks, or anything else to cover up the enclosure for aesthetic purposes.

If this is an option you are going for, then simple boxes, rather than flush enclosures, are easier to work with.

How can I make my recessed enclosures secure?

Medium and high security enclosures are necessary in many applications, including public places such as police stations, prisons, schools, and hospitals.

For these purposes, electrical enclosures need to be secure.

Thus, you can use 12 gauge steel for medium security and 10 gauge steel for high security.

Recessed enclosure with reinforced door

This prevents the enclosures from suffering the physical impact.

Plus, you can also request different locks, latches, and combinations for extra security.

How protected can my recessed enclosures be?

You can request your recessed enclosure to be compliant with either NEMA or IP standards.

We offer any NEMA type of enclosures, as well as IP rated enclosures up to IP66.

NEMA types go up to 13, with many numbers having lettered subtypes.

These types don’t ascend in strength necessarily, but rather outline specific properties they have, such as resistance to corrosive agents and coolant or oil leaks.

If you want to learn more, we also manufacture NEMA enclosures, and we have another very informative guide.

Moving on to the IP rating, it consists of 2 digits that correspond to protection against solid and liquid ingress, respectively.

Thus, IP66 means that the enclosure if fully protected against solids, such as dust and can withstand powerful water jets, as well as being temporarily submerged underwater for 30 minutes.

If you would like to learn more on this as well, we have an IP66 certification that you can take a look at.

IP rating and NEMA types do overlap slightly, and while it is not possible to convert one into another direction, it is possible to roughly equate them up.
