You're reviewing: MasterHeat Thermostat Relay 500880
Question:can I hook 2 81012096 cables to one thermostat either with or without a relay? thanks

Answer: Yes, as long as you do not go over the recommended Amps of the Thermostat. If you download the User Manual from our cable product page and look at table 5 on page 9 of the manual this will help. Also there is a chart on the product page of length of cable and it's total amp draw. Give us a call if you have any doubt and we can help you check.
