300 200 watt dump load. |Page 1 | 2 | 3
The centre terminal is the common ground or Negative for all bulbs. The copper wire I used was stiff enough to hold the bulbs upright.
Below is the circuit diagram. I've divided the dump load into two 100 watt switch able loads. The two switches each feed two bulbs. I need the fan to be running when either load is switch on, so I used a couple of diodes ( 1N4001 ), one from each switch.
