Letters and Comments

While investigating heaters with thermally damaged plugs from different manufacturers, U.S. Consumer Product Safety Commission (CPSC) technical staff[ found inconsistent crimping, welding and/or soldering on the crimp connectors of the heater plug blades.  Staff’s evaluations included x-rays and CT scans of incident and exemplar heater power cord attachment plugs, which showed inconsistencies on the crimps of the plug crimp barrels to the power cord conductors and/or welding or soldering of the plug connections.
