In NC we are required to report the location(s) and inspect all distribution panels. Ther NC SOP also says that we have to remove the covers on
“auxiliary distribution panels”.
A question came up today at the NCLHIA training seminar in Wilmington as to whether or not the HVAC single disconnect boxes are considered distribution panels.
The boxes or panels differ in many ways, some have only a switch, some use a breaker and some have larger size wire coming in than leaving.
(The post is only about the ones that have just one load device attached)
About half of the inspectors indicated that they do not open these.
I do open these since I find loose or burned connections in about 15 percent of them.
Does anyone have a definition of these that will indicate whether or not they are considered distribution panels?
