So I would be thrilled to hear that the cable actually goes from the switch to a low voltage power supply in the 12-24V range, which then powers 12-24V LED lights at the pole. Now the devices can still be used where exposed, but the concealed use has changed. Right?īecause these defects would not be of concern if this circuit were less than 30 volts and less than 55 watts.

Switch, outlet, and tap devices of insulating material shall be permitted to be used without boxes in exposed cable wiring and for rewiring in existing buildings where the cable is concealed and fished. National Electrical Code 2011ģ34.40(B) Devices of Insulating Materials. The 2011 version of the code had this to say. The use of these devices is limited to specific situations, which are described in 334.40(B) of the National Electrical Code.
