ANSI Device Numbers. From Wikipedia, the free encyclopedia. The ANSI Standard Device Numbers[1] [2] [3] denote what features a protective device supports (such as a. relay or circuit breaker). These types of devices protect electrical systems and components from damage when. an unwanted event occurs, such as an electrical fault.
The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. A chain slides across the surface of the sawbar rail at around 5000 feet per minute. The chain is moving at 55 to 60 m.p.h. or a mile per minute (88 feet per second).
You must take into account the cord gauge and the wire gauge because every foot of cord increases the electrical resistance, which decreases the power the cord can deliver to your chainsaw. And this is why you should only buy an outdoor extension cord no longer than is needed. Why buy a 100-foot cord to power your chainsaw if your yard is no further than 45 feet in any direction? Donât do that. It doesnât make any sense and it will compromise the power delivered to your electric chainsaw.
