Receptacles, switches & devices

What we install and replace

We install and replace standard and 20-amp receptacles, USB receptacles, GFCI and AFCI receptacles, weather-resistant outdoor receptacles and 240-volt receptacles. We install single-pole, three-way and four-way switches, dimmers, timers, occupancy sensors and smart switches.

Common jobs include replacing worn outlets that no longer hold a plug, adding outlets so you can stop using extension cords and replacing two-prong outlets in older homes. We also add switches for new lighting. If you are planning new fixtures, see our lighting installation and upgrades page.

Code rules for replacing outlets

Minnesota enforces the 2026 National Electrical Code, effective August 17, 2026. A replacement outlet must meet several current rules, even when the old one did not.

Two-prong outlets. If the box has a grounding conductor, the new outlet must be a three-prong grounding type connected to that ground. If there is no ground, the code allows three choices: another two-prong outlet, a GFCI receptacle marked "No Equipment Ground," or a three-prong outlet protected by a GFCI and marked "GFCI Protected" and "No Equipment Ground." A GFCI improves shock protection, but it does not create a ground. Some electronics and surge protectors still need a true ground, so we explain the options for your home.

Tamper-resistant and weather-resistant. In homes, replacement receptacles must be listed tamper-resistant where the code requires them. Outdoor replacements in damp or wet locations must be weather-resistant.

GFCI and AFCI. Where the code now requires GFCI or AFCI protection for that location, the replacement must be protected. Read more on our GFCI and AFCI protection page.

Switches, dimmers and smart controls

Most smart switches and many occupancy sensors need a neutral wire in the switch box. Current code requires a neutral at lighting switch locations in habitable rooms, with some exceptions, but many older Twin Cities homes were wired before that rule. We open the box, check what is there and tell you which devices will work.

Dimmers must match the lamp type and the total load on the circuit. An LED fixture on the wrong dimmer can flicker, buzz or fail early. We check the fixture and dimmer compatibility before we install.

Safety and when to call

Swapping a device is small work, but it is still electrical work. Minnesota requires a license to perform electrical work. The one exemption is for a homeowner who does the work personally on a home they own and occupy, with a permit and inspection. Any time you open a box, turn off the breaker and confirm the power is off with a tester.

Stop using an outlet or switch and call us if it is warm, discolored, sparks, buzzes or smells like burning. Those signs can point to a loose connection that heats up behind the wall. For problems across several outlets or rooms, see our electrical troubleshooting and repair service. For burning smells or sparks, call our 24/7 emergency line at 651-488-5555.

Signs you need outlets or switches replaced

• Plugs fall out of an outlet or fit loosely
• An outlet, switch or cover plate feels warm
• You see scorch marks, cracks or melted plastic on a device
• A switch buzzes, crackles or sparks when you use it
• Your home still has two-prong outlets
• You rely on extension cords or power strips because there are too few outlets
• Lights flicker on a dimmer after you changed to LED bulbs
