    Safety Switches

    Hi,

    I generally deal with just residential PV design, but I'm beginning to tread into commercial design these days. I am dealing with a 3-phase, 208Y/120VAC system, and I am in the process of spec'ing my AC disconnect. I notice there are many 3-pole AC disconnects rated 240/120VAC, and some rated 600VAC. Would the 240/120VAC be suitable for a 208Y/120VAC system?

    Regards,
    Andy

    Yes. The 240V disconnects are rated for any circuit that is 240Vac nominal or less between any possible pair of conductors within it.
