At certain venues  I have to run the Tyros, Wireless mic and Powered speakers through a 25 ft. extension chord. 

The required amperage appears to be a low for the equipment.  There are trade offs for going for a lower gage chord namely flexibility, cost, and weight. 

Curious what gage chord people are using , and if they have experienced any damaged equipment with a higher (cheaper) gage extension?

Regards,

Jerrghr

I tend to stick with major 7th's, flatted fifths, augmented ... well, you get the idea smile.

Seriously though, depending on the powered speakers, at only 25ft, 16 ga. should be just fine (especially if your powered speakers are using class D amps, the rest of your SS equipment uses very little juice).

Thanks Chas for the input. I never had a problem with extension chords except or a leaf blower that would overheat with a 16 gage extension. Went to a better chord and problem was solved.

Just wanted to make sure it wouldn't be a problem with musical equipment.

Regards,

Jerryghr

It all depends upon the wattage. Anything over 400-watts total passing through a 25-foot extension cord would require 14 gauge. Over 600 watts, go with 12 gauge. The higher gauge wires would have a significant voltage drop with high wattage systems.

Good luck,

Donny, that power strip only has a 15 foot extension cord. He was asking about a 25 foot cord, which makes a huge difference. I know, 10 extra feet doesn't sound like much, but when it comes to heavy loads and voltage drop, that extra 10 feet can make a huge difference if the wire gauge isn't capable of handing the load.

All the best,

Gary cool

Thanks again for the info.

Looks like I'll make sure I get a 14 or 12 gage extension depending on the flexibility. I hate fighting with the "Electric Spaghetti"

Regards,
