The National Electrical Manufacturers Association (NEMA) has published DC 10-2009 Residential Controls—Temperature Limit Controls for Electrical Baseboard Heaters. The publication revises the 1983 version, which was reaffirmed in 1989 and 2003.

DC 10 defines the basic standards for rating, classification, construction, testing, and performance of temperature limit controls for application on electric baseboard heaters. These controls or controls systems, of either the automatic- or manual-reset type, are responsible for disconnecting the electrical load when the heater reaches abnormally high temperatures.

Revisions include the addition of metric units and updates to the voltage ratings and marking requirements.

According to Tuong Nguyen, a member of NEMA’s Residential and Commercial Controls Technical Committee, “DC 10 was designed to promote direct interchangeability of temperature limit controls for electrical baseboard heaters through industry standardization, and assist users in selecting the proper controls for a particular application. This new revision will be very helpful for residential home builders and electrical contractors.”
