Thanks for your electrical question Philippe.

How to Install Programmable Thermostats

Application: Installing programmable thermostats for baseboard heaters.
Skill Level: Beginner to Intermediate – Best installed by a Licensed Electrician.
Electrical Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on personal level experience and ability to work with tools.
Precaution: Identify the circuit for the furnace or heat pump, turn it OFF and  Tag it with a Note before working with the thermostat wiring.
Troubleshooting and Testing: Most thermostats may be tested using a Volt/Ohm Meter. The thermostat battery should be tested and replaced as needed.
Notice: Make sure to get the exact replacement thermostat.

Electrical Tip

The Safest Way to Test Electrical Devices and Identify Electric Wiring!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

    I am building a powder coating oven from electric range stove and I installed 6 burners. What kind of thermostat can I use to manage all the burners at once?

    • Dave Rongey says:

      Hi Ian,
      Typically a thermostat is rated for the amperage or watts and the voltage, therefore this information and the total capacity for all of the combined burners will need to be determined to locate a thermostat. The throttling range of the thermostat may also need to be considered which will determine at what temperature the burners are turned on, and off. In some applications it may be best to have a control circuit where the thermostat activates one or more relays which are rated appropriately for the amperage loads of the application.
      Be safe,
