Victor load testing

This sure provoked some interesting suggestions! My favorite is the salt water swimming pool...

At lunch I went over to the electronics store and bought 10 3.6 ohm 25 watt resistors. We'll wire them in parallel, in two banks of 5 each, so we can test with either (approx) 450 or 225 watts load at full power (12.8 volts). This should give a max current through the Victor of about 36A, a reasonably safe 10% below max rating for it. These are rectangular concrete resistors, so we can cool them with a slab of steel laid across all of them that will have pretty good surface contact, and keep the full power tests reasonably brief, since at max the resistors will be dissipating about 46 watts of heat each, substantially over their 25 watt rated limit. The steel will also protect from the shrapnel if they blow up....

Thanks again for the ideas.

Bill
