These power blocks are rated 175 A and 600 V for electrical applications in power panel distribution. The blocks can also be used for lighter power applications and, therefore, have extended utility as a one-size-fits-all product line.
Bob and Tim are on a service call on a really cold and blustery day. The temperature is 27°F, the wind is blowing, and it’s snowing and sleeting.
