I am not sure if this is the correct location for this question

could someone tell me were to fine the standard hieghts in commerical and industrial buildings for receptacles and light switches


I have been told that receptacles need to be 18" above the floor not sure about the light switches 48 or 54 and 42 for ADA

not sure if this infromation is listed in the code

thanks

Every commercial job or plans I have seen have those measurements on the specs. I don't know that there is an industry standard. Plans will tell you a swich is 48" AFF, and even then you need to verify if it is bottom of box or center, not to mention the difference in your rough floor and finished floor so you can adjust.
 
thanks for all your help I did not think it was a code question

on other question of this topic if you could

I have 2 opinions on this

placement of interior light and extrior light switch

I have always placed the exterir light switch next to the door and the interior switch inboard

andthing on this

thanks
 
switch

switch

I believe the only place that NEC states where switches are to be located are for attic and crawl space lighting and on each level for stairwells....other than that it's your call. your kitchen light switch can be in bathroom, etc.
