[QUOTE="Rob Timmerman, post: 24761, member: 172"] Re: When L21-30 just isn't big enough Just because your particular setup only has line to neutral loads doesn't mean that you can't plug in a device connected line to line. What if you have a subrented piece of gear with line to line loads (like a motor distro with 3-phase motors)? If you lose one hot leg, the motor might still keep turning. Or you lose the return path for the amplifier running at 208V, so the amplifier is off but the other phase is still hot. This is the primary reason that the poles of the breakers must be linked, and why you shouldn't cut those links. [/QUOTE]
