Electrical work can cause shock, burns, arc flash, fire, equipment damage, carbon-monoxide exposure and death. Energy Clarity provides educational information and decision frameworks, not site-specific engineering, wiring instructions or a substitute for codes, permits, manufacturer instructions, utility requirements or qualified professionals. Do not connect experimental devices to household wiring or the utility grid without proper design and authorization. Never backfeed a building through an improvised generator connection. Combustion generators must be operated according to manufacturer instructions and away from enclosed or partially enclosed spaces. Stored-energy and solar systems can remain hazardous even when some controls are off.
