Wire specs - dummy load

I'm in the process of building a switchable, 4/8 ohm, dummy load device for use in testing audio equipment. My immediate need is to test a set of tube, mono blocks each outputting around 50 watts (20 v into 8 ohm, like 3 amps); but I think I should build the device to accommodate larger units: say tube amps up to 150 watts and SS up to 200 watts.

I have two pairs of 8 ohm and 4 ohm, 100 watt, dummy load type resistors, but I would appreciate advice on what size hook-up wire to use. (I've got some 22 AWG, 600V wire on hand, but I hate to use it up if it would be over-kill.

Thanks.
 
22 AWG has about 6 Amps rating. For short time tests you can overload wire a bit.
