Wire specs - dummy load

[wanders]

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.

And it´s not overkill by any means.
Voltage is not an issue, current is near maximum , most peopple would wire it somewhat thicker wire, "just in case".
It does not hurt.

Thanks, guys. Actually, I've still got some older, 600 Volt wire with heavier insulation. 22 AWG claims to be the same, but I'll use the old stuff.

I might use 12AWG or better yet, four 14AWG wired as a StarQuad with lots of twists.

Or use wire from old line cords.
