I am installing an isolating transformer with electrostatic sheild for a music recording studio 240 volt(60 amps) in and 240/120 out. it is in a residential house that has no steel. my question is does this sound like proper application/installation for this job(haven't done x-former in ions)i pull 3-#8's(copper)two phases tied to primary (h1+h4 and h4+h10), one ground (to factory provided lug) from new sub panel(feeds non isolated loads) in music room through 3/4" EMT to jbox,then whip into x-former. at x-former i install a double barrel lug to frame of x-former and tie x2 and x3 from secondary to oneside of lug and feed isolated sub-panel neutral from this bonding point. then bond single lug on frame and run to ground bar of my isolated sub-panel and feed isolated sub-panel from x1 and x4. does this sound right? or did i miss something? thanks in advance,
