What will get overridden- the turning on or the turning off? George I'm glad you requested as that's one thing I have wondered. Most of the wall switch motion sensors I have installed can only be overridden to the 'off' mode. To override them to 'on' often means moving into the adjustment section. Right here is the exception George is asking about. I've a related query. 110.26(D) Illumination. Illumination shall be supplied for all working areas about service gear, switchboards, http://vinculacion.udla.edu.ec/forums/forum/ideas-y-vinculacion/ panelboards, or motor control centers put in indoors. Additional lighting retailers shall not be required where the work house is illuminated by an adjoining mild supply or as permitted by 210.70(A)(1), Exception No. 1, for switched receptacles. In electrical tools rooms, the illumination shall not be controlled by computerized means solely.
