Required Dedicated Branch Circuits
When a home inspector hears “dedicated electric” and “required” they immediately think of a code requirement. In fact, there are code requirements for new builds. The code for new builds will also apply if you are renovating an older home that requires a permit. In some municipalities, that permit does not even have to be for electrical. If an electrical permit is issued, the new construction and in some cases, the existing electrical must be brought to modern standards. Depending on the size and amenities of a kitchen, there may be up to 7 dedicated branch circuits required. We are not conducting a code inspection, however there is sound advice we can give our clients. We have all inspected older homes with 4 dedicated circuits for the entire house!
- So how can a home inspector properly advise a client on dedicated electrical circuits in an older house?
- 2 – 20 amp, 120 volt circuits for the kitchen counter tops (1 may supply the refrigerator)
- 1 – 20 amp;, 120 volt circuit for the kitchen microwave / exhaust fan
- 1- 15 amp, 120 volt circuit for the furnace / boiler
- 1 – 20 amp, 120 volt circuit for the laundry room
- 1 – 20 amp, 120 volt circuit for each bathroom
- 240 volt circuits should always be dedicated, unless manufactures installation allows for it
- Dedicated circuits should be installed for a dishwasher and garbage disposal
- As a rule of thumb, most homes should have at least 100 amperes, 240 volt main service.
- If the service appears undersized, or there is some question as to the adequacy, a licensed electrician should be consulted with
