Burning Smells
Electrical smells are typically caused by parts overheating. Sometimes loose electrical connections cause wires or plastic relays to overheat.
A burning smell may be accompanied by smoke. Burning and electrical smells are severe matters for Thomas Edison Electric to correct. Don't delay! According to the Electrical Safety Foundation International, more than 300 deaths and 4,000 injuries due to electrical hazards occur in the workplace each year (esfi.org).
