Electrical Question: How many receptacle outlets can you wire onto a 20amp circuit breaker?
This electrical wiring question came from:
David, a Handyman from Millmont, Pennsylvania.
Thanks for your electrical wiring question David.
The Number of Electric Outlets on a Circuit
Application: Wiring Receptacle Outlets.
Skill Level: Intermediate to Advanced. This electrical wiring project is best performed by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and the number of outlets that will be replaced.
Precaution: Identify the outlet circuit, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Installing additional outlet wiring should be done with a permit and be inspected.
Planning Electrical Wiring for Outlet Circuits
- Identify the Area where the Outlets will be Installed
- The answer to this question of how many receptacle outlets can be wired to one circuit will be relevant to the location of the receptacle circuit and what the outlets will be used for, or the designated use for the circuit as it pertains to the load that will be placed on the circuit.
- This will include identifying specific equipment or devices that will be connected to the circuit.
- As the definition of the circuit is identified then we will need to see if there are specific codes that must be followed in order to be code compliant.
- Electrical Codes and Outlet Circuits
- The code is very clear about certain circuits that are installed in some locations of the home. Even more than this, the actual type of circuit may be addressed as well, such is the case for bedroom outlet receptacles.
- Bedroom Outlet Circuits
- Bedroom outlet circuits must be protected by an AFCI circuit breaker, or an AFCI receptacle outlet must be installed in the first position of all the other receptacle outlets.
- For bedroom areas it is common to have ten to twelve outlets on one circuit, which may be 15 amp or 20 amp.
- Keeping in mind the loads that are placed on some bedroom circuits by a busy family, it may be best to have two bedrooms on one twenty amp AFCI circuit, if the exact intended load will allow.
- Kitchen Outlets and Small Appliance Circuits
- The kitchen is another example where specific circuits must be installed and loaded according to the national electrical code.
- Kitchen counter top receptacle outlets used for small appliances is another example.
- Small appliance kitchen circuit must be twenty amp with GFCI protection, and a minimum of two of these circuits are required.
- The Size of the Home
- The actual number of circuits will depend on the size of the home.
- In larger homes, it is very common to have four or more twenty amp circuits that are serving counter top receptacles.
Electrical Tip when Planning Electrical Wiring for Outlet Circuits
- Identify the intended use for the circuit.
- Identify the location of the circuit.
- Consult the National Electrical Code for specifics based on the identified circuit.
- Consult your local building authority to see if there are any additional requirements.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
