    We will need more information to help are the heaters 120v or 240v, what is the wattage of the heaters and last what kind of thermostat single pole , double pole , bimetallic or electronic . All the above information will make a difference on how to connect everything. – Ed Beal Oct 15 at 13:29
  • red and black like you're in the Philippines or Japan? North American /2 cable is normally Black-White-ground. Do you have /3 cable that is Black-White-Red-ground? – Harper - Reinstate Monica Oct 15 at 14:17
  • In Canada, red 12/2 gauge wire 240v with red, black and ground wire. One heater 750w and 1500w. Thermostats are digital and programmable. – R.J Oct 15 at 15:33
  • As Ed Beal asked, are the thermostats single pole or double pole? That is, do they have 2 connection points, or 4 connection points? – kgc Oct 15 at 17:10
  • The thermostats are single pole. – R.J Oct 15 at 17:28

In the first junction box with the first thermostat, connect with wire nut black wire from panel, black wire to next junction box, short pigtail wire to thermostat. Connect with another wire nut red wire from panel, red wire to next junction box, red wire to first heater. Connect black wire to heater to other connection on thermostat. Connect ground wire from panel to junction box then to wire nut, with ground wire to second junction box and to heater.

In the second junction box with the second thermostat, connect black wire from first junction box to thermostat. Connect red wire from first junction box to red wire to second heater. Connect black wire to heater to other connection on thermostat. Connect ground wire from first junction box to second junction box then to wire nut with ground wire to second heater.
