4. Electrical Code/Drafting Practice Duplex convenience outlets (wall plugs) should be a maximum of 12’ apart. Closer spacing is desirable, although economy is a factor. Code reads: “no point along a wall is further than 6’ from an outlet.” Duplex convenience outlets should be no more than 6’ from a corner There should be a duplex outlet in any usable wall space over 2’ long Place a (one) duplex outlet in a hallway

5. Outlet Placement Example

6. Electrical Code/Drafting Practice Kitchen /Bathroom areas –usable counter space of 12” & greater require an outlet –outlets are required every 48” of counter space (with new code text is in error) –note mounting height for outlets above counter (+44”) –special purpose outlets for garbage disposal, dishwasher, separate oven, and hood –range outlet for electric range –GFI or GFCI protection for any outlets in rooms with a water source.

12. Electrical Plan Example

13. Special Project Elect Plans (50 Points) Add electrical symbols and all electrical information to your plans: –Foundation plan (3 light +switch, one outlet and special purpose outlet for water heater) –First level floor plan (two exterior WP outlets, lights at all entrances, elect range w/ hood above, garbage disposal, dishwasher outlet, and washer/dryer outlets) –Second level floor plan (exhaust fans in bathrooms, 3- way switch to 1st floor for stair light) –Complete an electrical schedule (10 points) for all the symbols used similar to one shown in Handout

14. Electrical Symbol Schedule Purpose of schedule is to identify and describe electrical symbols used in the set of working drawings Categories –Symbols –Descriptions
