standard power socket only up to 13amp / 2000watt.
Cal-Lab 10amp can support up to 1.5hp air con.
if you have requirement for 3500watt, your PC setup is almost about total 3.0hp air con total consumption. you sure for that?
nope, Cal-Lab dont have ELCB or MCB unit. it simply a "middle man" between the wall power socket and your equipment.
TRM series have universal socket but usually come with 1x universal + 2x UK.
