Draw an electrical plan — outlets, switches, lights, and symbols
Open the Symbols panel, tap a wall to drop an outlet or switch, name each one with its breaker number, add lights and low-voltage symbols, and print a clean electrical plan with the names on it.

Label Outlets & Switches With Circuit Breaker Numbers on a Floor Plan
Name each outlet and switch with its breaker number, show the names on the plan, draw the circuit, and print it.
An electrical plan is the one drawing almost every renovation needs: where the outlets go, which wall the switch is on, where the lights hang. RoomSketch3D keeps all of it in the Symbols panel, the tab after Indoor and Outdoor on the right (or the Symbols pill on a phone).
There are two kinds of symbol, and they place differently. Wall-mounted devices — outlets and switches — are placed by tapping a wall, exactly like a door or window, and they sit flush on that wall. Free symbols — ceiling, recessed and wall lights, fans, smoke detectors, data jacks, cameras, vents — drop into the room like a piece of furniture and can be dragged anywhere; free symbols appear on the 2D plan and in exports, not in the 3D view.
Everything you place shows up in every export and print, and there is a dedicated Electrical plan export style that hides the furniture and colour fills so an electrician sees only the shell and the devices.
Mapping your circuit breakers? Give each outlet and switch a name such as Breaker 12 and it shows next to the symbol on the plan and on every print. The step Label outlets and switches with breaker numbers below walks through it.
What you'll need
- •Any floor plan with walls (a single room is fine)
- •Desktop, iPad, or phone — the Symbols panel is on all three
Step by step
- 1
Open the Symbols panel
In the right-hand panel, tap the Symbols tab (after Indoor and Outdoor). Tabs at the top pick the outlet and switch pack: US, Europe or All (it opens on the one that matches your units and then remembers your pick). Lights, detectors, plumbing, HVAC, telecom, security and markers are shared by both packs. Search filters everything, and your own uploads appear under My Library.
Symbols sits beside Furniture. Tiles are grouped by trade; search filters them. - 2
Place an outlet on a wall
Tap Outlet (Duplex) (or Outlet (Single) for a single receptacle), then +Add. The banner reads Outlet (Duplex): tap a wall to place it — tap the wall where the outlet goes and it snaps flush to that wall. Add as many as the run needs; most codes want a receptacle within six feet of any point along a wall, so roughly one every twelve feet. Outlet (Quad), Outlet (GFCI), Outlet (240V), Outlet (USB) and the other outlet types place the same way, and each draws its own standard symbol on the plan, so your electrician can tell them apart. The full list is in the FAQ below.
Wall-mounted symbols are a tap-a-wall placement, not a drop. - 3
Add a switch beside the door
Tap Switch (Single) → +Add → tap the wall just inside the entry door, on the latch side where a hand naturally lands. Switch (Double), Switch (3-Way) and Switch (4-Way) are there for two-gang boxes and circuits controlled from two or three places, plus Switch (Dimmer) and Switch (Smart). Each draws its own symbol on the plan.
Put the switch on the side of the door the handle is on. - 4
On an interior wall, choose the side
An interior wall has two rooms facing it. Tap the wall to place the outlet or switch, then in the inspector under Sides pick In or Out to choose which face — and therefore which room — the device serves. The symbol flips to that side of the wall on the plan and in 3D.
Interior walls expose an In / Out toggle: the room the device faces. - 5
Label outlets and switches with breaker numbers
Select the outlet or switch (tap its symbol beside the wall). Its panel opens along the bottom, and the box at the left holds its name, which starts as Outlet or Switch. Tap the box, clear the old name, type the breaker number, for example Breaker 12, and press Enter (on a phone, tap the green check). Name every device on that breaker the same way. Only a name you typed is shown on the plan; a device still called Outlet stays unlabelled.
The name box is the first thing in the outlet's panel. Type the breaker number and press Enter. - 6
Show the names on the plan
Outlet and switch names show on screen together with furniture names. Open Layers (the stacked-sheets button in the toolbar above the plan) and tick Show furniture labels. Each name appears beside its symbol. On a computer this is off when you start, and on a phone it starts off too, so this is the step people miss. A selected device always shows its own name.
Layers → Show furniture labels shows outlet and switch names. - 7
Check every device has its number
With labels on, read along each wall: every outlet and switch should carry its breaker number. Two outlets on the same breaker can share a name. Furniture names show too while this layer is on; the Electrical plan export below leaves the furniture out.
Names sit next to their symbols: Breaker 12, 14 and 15. - 8
Print or export with the names
Open Export / Print / Share (top right) and choose PNG/PDF or Print. Under Options, keep Labels ticked: that is the switch that prints outlet and switch names (and room and furniture names). Tick Electrical plan for a sheet without furniture and colour fills. Then use the Print tab, or Export as PNG or PDF. If you work on a phone, Labels starts unticked, so tick it first.
Labels prints the names; Electrical plan hides the furniture. - 9
Your printed breaker map
The exported plan shows every named outlet and switch with its breaker number beside the symbol, and a circuit line's name along its dashed run. A Symbol legend under the drawing lists each kind of device with its count. Tape it inside the panel door, or hand it to your electrician.
The exported PNG: names print next to each symbol. - 10
Drop lights and low-voltage symbols
Free symbols behave like furniture: tap Ceiling Light → +Add and it lands in the middle of the room; drag it to where the fixture hangs. Do the same for Recessed Light, Ceiling Fan, Smoke Detector, a Data Jack, a CCTV Camera, or an HVAC Supply Vent. Select any symbol to resize it, colour it, or rename it in its name box (a light can be Breaker 7 too). To see that name on the plan, tap the tag button (Show label below symbol) with Show furniture labels on.
Lights, jacks, and cameras drop at the room centre and drag anywhere. - 11
Export the electrical layer
Open Export / Print / Share → PNG/PDF or Print. Under Options, tick Electrical plan: furniture and colour fills are hidden, leaving the shell, the symbols, and the light fixtures. A symbol legend under the drawing lists every kind of outlet, switch, light and symbol on the plan, with how many there are. Keep Labels ticked if your devices have names. Combine it with Black & white for a pure line drawing, or add Elevation views as extra pages. Symbols print on every export too.
Options → Electrical plan: just the shell and the devices.
Tips
Outlets go on walls, lights go in rooms
If a symbol won't drop where you tap, check its kind: wall devices need a wall under the tap; ceiling and low-voltage symbols need a tap-free +Add, then a drag.
Search by trade word
Type outlet, switch, vent, jack, or camera in the Symbols search — the library is filtered instantly, including your uploads.
Plan the switch where the hand lands
Inside the door on the latch side, about 48 inches up (the default mount height). For a room with two entrances use Switch (3-Way) at each.
Next: connect them
Once the devices are down, the Circuit line tool links them into runs, and you can name each run after its breaker too — see circuit lines.
One name, one breaker
Use the same wording everywhere (Breaker 12, not B12 on one outlet and Circuit 12 on the next), so the printed map reads like the labels in your panel.
Common mistakes
Placing an interior-wall outlet on the wrong face
The default side is the room you tapped from. Check the In / Out toggle — a bedroom outlet accidentally facing the hallway is the classic miss.
Exporting with furniture still shown
A furnished plan buries the symbols. Use the Electrical plan style so the trades see only what they need.
Hunting for outlets in the Indoor tab
They live in Symbols. The Build panel holds structure (walls, doors, stairs); Symbols holds trade markup.
Typing the number after the old name
The name box keeps Outlet until you clear it, so typing straight in gives OutletBreaker 12. Select the old text first, then type.
Naming devices but leaving labels off
Names are saved even when you can't see them. Turn on Layers → Show furniture labels to see them on screen, and keep Labels ticked when you print or export.
Frequently asked questions
Can I put an outlet on an interior wall?
Yes. Outlets, switches, mirrors, and wall safes place on interior walls as well as exterior ones. The inspector's In / Out toggle picks which side of the wall — which room — the device faces.
Do the symbols show up in 3D?
Partly. Outlets and switches placed on a wall show on that wall in the 3D view. Free symbols — lights, fans, detectors, jacks, cameras, vents, and your own uploads — appear on the 2D plan and in every export and print, but not in 3D.
How do I get a plan that shows only the electrical layout?
In Export / Print / Share → PNG/PDF or Print, tick the Electrical plan option. It hides furniture and colour fills and keeps the shell, symbols, and light fixtures.
Is there a plumbing or HVAC set too?
Yes. The Symbols library includes shut-off valves, floor drains, hose bibs, a water heater, thermostat, supply and return vents, phone and data jacks, Wi-Fi access points, CCTV cameras, and generic markers — plus anything you upload yourself.
How do I label outlets and switches with breaker numbers?
Select the outlet or switch, clear the name box at the left of its panel, type the breaker number (for example Breaker 12) and press Enter. Turn on Layers → Show furniture labels to see the names on the plan, and keep Labels ticked in Export / Print / Share → PNG/PDF or Print so they print. You can also name a circuit line after its breaker.
My outlet and switch names don't print. What's wrong?
Check four things. 1) In the Export / Print Floor Plan dialog, Labels must be ticked; it prints the names (on a phone it starts unticked). 2) The device needs a name you typed: one still called Outlet or Switch has no label. 3) Outlet and switch names need the latest version of the app (names on printed plans arrived on October 3, 2026), so reload the page or update the app. 4) An outlet with a dashed amber outline was dragged onto the plan before October 7 and isn't attached to a wall yet: select it and tap Attach to nearest wall. Names also print in PNG and PDF exports; the DXF (CAD) export does not include outlets, switches or their names.
Which outlets and switches are in the library?
US pack outlets: Outlet (Single), Outlet (Duplex), Outlet (Quad), Outlet (GFCI), Outlet (20A), Outlet (240V), Outlet (Weatherproof), Outlet (Switched), Outlet (USB), Outlet (Tamper-Resistant), Outlet (Isolated Ground), Outlet (AFCI), Outlet (Range), Outlet (Dryer) and Floor Outlet. US switches: Switch (Single), Switch (Double), Switch (3-Way), Switch (4-Way), Switch (Dimmer), Switch (Smart), Switch (Pilot Light), Switch (Key), Switch (Timer), Switch (Occupancy Sensor), Switch (Weatherproof) and Switch (Low Voltage). The Europe pack has earthed, unearthed, double, triple, switched, outdoor IP44, USB and 400V 3-phase sockets, plus one-way, 2-gang, two-way, intermediate, dimmer and push-button switches. Shared by both: ceiling, recessed, wall, pendant, track and under-cabinet lights, a ceiling fan, an Electrical Panel, smoke, CO and combined detectors, a doorbell, a motion sensor and a junction box.
The symbol I need isn't there. What can I do?
Pick the closest standard symbol and name it (for example an Outlet (Duplex) named Breaker 12 – 30A twist-lock), or draw your own and add it with Upload custom symbol in the Symbols panel. An uploaded symbol drops into the room like a light rather than onto a wall, so it doesn't appear in 3D, but it can be named, labelled and joined into circuit lines. Send the list of symbols you're missing through Support; those requests decide what's added next.
