Thanks for your electrical question Timothy.

Garage Electrical Wiring for Outlets and Lighting

Application: Electrical Circuit Wiring in a Residential Garage.
Skill Level: Beginner to Intermediate. This electrical wiring project is best performed by a Licensed Electrical Contractor or Certified Electrician.
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 GFI outlets that will be installed.
Precaution: Identify the circuit at the electric panel, turn them OFF and Tag it with a Note before working with the outlet wiring.
Materials: Materials used for electrical circuit wiring should be of the same amperage and voltage rating as the existing electrical circuit.
Notice: Installing additional Electrical Wiring should be done according to local and national electrical Codes with a permit and be inspected.

    Hi David,
    There are no height requirements for garage outlets, however as you have stated, it is better to have the outlets higher rather than low, especially if a work bench will be located inside the garage. Having access to the outlets will be very helpful.
    I hope this helps,

  2. David says:

    Are there any height requirements for outlets in the garage. Seems like higher would be better. Thanks

  3. Dave Rongey says:

    Hi Randy,
    The NEC Electrical Code Section 210, specifically Article 210.52(G) states that one receptacle outlet is required for each car space,and NEC Article 210.8 (A)(2) states that GFCI protection is required for all 120volt 15amp and 20 amp receptacles. 120volt, 15amp garage circuits are typically wired with 14/2. If the circuit is wired for specific equipment then the amperage and wire size will be based upon the equipment specifications or applicable NEC Electrical Codes.
    Thanks for sharing your garage electrical code question,

  4. Randy says:

    Is it allowed by the NEC Electrical Code for the GFI plugs in the garage to be on 14/2 wire?

    Hi Scott,
    Most spec homes or track houses are built as inexpensively as possible, however they are up to the current building and electrical code requirements at the time of construction. When a custom home is built there is typically more planning and discussion about specific needs and preferences for outlets, lighting and other electrical devices. Depending on the home development company or the general contractor there may be a higher standard which will include more convenience devices such as additional outlets in the garage. When building a new home or remodeling an existing home it’s always a difficult decision to make about where to draw the line for adding more features. The end result will effect the overall budget of cost of the construction project. Adding additional circuits or outlets after a home is built is possible, however it is always more labor intensive and costly than during the initial construction phase.
    Thanks for sharing with us Scott,

    What is the least quantity of outlets in a garage? I have a new home with one outlet in 2 car garage, and two outlets in the ceiling for the garage door openers which have not much access. There is only one usable outlet. Its seems hard to believe in a huge garage that there is only one outlet on wall.

  7. Dave Rongey says:

    Hi Stephen,
    Accessible general purpose outlets in the garage should be protected with GFCI. Exceptions are for single outlets (not duplex) that are for specific equipment such as a whole house vacuum system and ceiling mounted garage door opener. Refrigerator and freezers located in the garage have a history of causing GFCI outlets to trip off, therefore the outlet for these devices are not required to be GFCI protected as long as the outlet is not readily accessible, or if it is a single outlet.
    One additional thought here is that the garage circuit wiring should be configured so that a tripped GFCI circuit breaker or outlet does not leave a person in the dark.
    I hope this helps,

  8. Stephen says:

    Are GFCI outlets required for all outlets in the garage (Florida) ? I’ve been given variable answers depending on if it’s for a freezer or if it’s on the ceiling then no, etc..but want to know for sure to be safe? Thank you!
