ECN Forum Forums General Topics of the Trade General Discussion Area Siemans generator breaker interlock?

Does anyone know if Seimans make a interlock for generator mains like Square D does, that prevents generator breaker coming on while utility power is on??? Thanks Steve.....
Not sure about the spelling of Seimans or Siemans

Reliance Controls makes a UL listed panelboard that has a two interlocked siemens breakers called panel-link. I think it is proprietery to Reliance Controls.
