NEC compliance with regard to TVSS fusing
With regard to NEC Articles 280 & 285:
1) Is fusing of TVSS circuits in compliance? If so, what are the acceptable sizing guidlines? Blown fusing, while protecting the TVSS equipment, would leave the equipment exposed to future spikes, which appears to be in violation of the articles.
2) What are the seperating differences between "surge arrestors" and "TVSS"?
