Whole house surge protector wiring question
I'm helping a friend of mine who wants to install a Panamax GPP8005
whole house surge protector, which gets mounted next to the main panel. The instruction say it can be connected to the main panel using either a double 30 amp breaker or preferably using a sub-feed lug kit. The picture of the unit shows it with wires coming out, ready to be attached. So, I understand the connection method using the breakers. But, if we followed the directions and connected it using a sub-feed lug kit, wouldn't that be a major code violation? The only protection then would be the main panel 150 amp breaker, which would be incompatible with whatever gauge wires are coming out of the surge protector, because if they can connect to a 30 amp breaker, they surely can't handle 150 amps. So, am I missing something here? Here's the install instructions and pics if you want to look: http://www.smarthome.com/manuals/4839_new2003.pdf |

They only have to be able to carry the current long enough to blow the main breaker. That should only take a a second or so, not hours as if the thing was actually using any power so to speak of. |

No other opinions on this? I was hoping someone could spell out how the code allows this? |

Look about half way down :http://www.sea.siemens.com/step/pdfs/surge_2.pdf Thanks for pointing me in the right direction. The Siemens article talks about NEC 280 that covers this stuff. Some googling on that produced more good stuff. |
