260W dummy made of 3x 50W resistors - I know they're overloaded much but they work without problems with sub-zero temperatures . 230V powered . Alu plate 10 mm thick

225W dummy made of 4x 50W resistors .230V powered . Alu plate 10 mm thick . That box is "cut-off" which should turn off dummy when I forget to switch it off after test and dummy is going to be very hot - it should turn off 230V when alu plate reach 70*C, unlucily it turn if off also when alu is very cold - I mean test on -100C evap cascade, it turns off power too . When I test SS with around -50C it's OK, safety cut-off can be turned ON, it not cut in such sub-zero temps . That's why I make ON/OFF switch on that safety device.
Hello Peter, how much Ohms does each Resistor have and did you wire them in series or in parallel?
