Soundhound :
quick question I thought you might have the answer too.

I bought the Tripplite isobar 8 - and plugged it into a 3 prong outlet (grounded), and the diagnostic lights indicate a fault in my wiring - which could be possible, this is an older home - BUT when I plug in any equipment to the isobar, the diagnostic lights - "say" that I am protected , and the line is fine -

which is correct ? any suggestions ?

Thx. Bryan
