for USA, Canada and countries running a 60 Hz power supply service.The NEC specifies the NECA-1 standard for general practices. NECA-1 lists typical mounting heights of different devices. This specification is not currently enforceable, but if you want standard heights, here you go:

Wall Switches: 48" / Receptacle Outlets (general): 18"

Receptacle Outlets (kitchen, utility room, etc) 42" or 6" above countertop

Telephone Outlets: 18" / Wall Intercom Stations: 48" / Wall Lighting Outlets: 84"

Thermostats: 48" / Bed Lights: 72"

There are more, but mostly used in commercial work.

All heights are from the top of the finish floor to center of box.

A typical height is 18" off the floor. However you can generally put them at any height you think would be most convienient. Keep in mind, however, if they are significantly different then normal it may cause your house to be harder to sell in the future.

I don't know of any building codes that specify a height but you should check by calling your town building department, just in case.


Your city building inspector can answer that one and you also need to know where the electrical outlets need to go. Almost all cities and towns adopt a uniform building code so I'd do an on line search for it. If you find the requirements for New York City they are probably the same as in Small Town USA.


In USA 12" to the center of the outlet is typical for most applications. Basement, laundry and utility rooms 3-6". 4'-0" in bathrooms and garages.


There is no height rule for receptacles in USA

Receptacle height is a matter of personal taste and practice.

General area receptacles in residences are commonly 12", 16" and 18" center, vertical installation. Older homes with existing devices in baseboard can be matched. Floor receptacles are allowed.

Answer for countries in Europe and other world areas running a 50 Hz power supply service.In the UK, in a new house it is a requirement to install light switches no higher than 1200 mm from floor level. For an extension they should be no higher than in the existing house.


As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

What is the proper height to mount a switch or receptacle in operation rooms?

Most areas in the US must comply with ADA, the Americans with Disabilities Act. This means switches and other devices with operable controls go 48 inches AFF (above finished floor), measured to the switch handle (which means to the center of the box). This is the maximum height permitted by ADA. Receptacles don't seem to have a real standard, I have seen from 12 to 18 inches where I work. If there are existing recepts in the building, we match those. At my house, for instance, they are set 12" to the top of the box.
