How do I cable up a 10kw generator to my house from garage?
Edit. I may have mis read so the second half is about tie in this first part is support of a cable: thanks @Izzy +
If talking about a cable grip like a U eye weave split lace.
these provide support to a cable like those finger locks but they wrap around and are laced together.
There are weaves that are not split but then you have to feed the length of cable from to the point of support .
one of my small ones is an L9575  1-1/4-1-1/2” cable size get ready for some sticker shock these run 60-70$ and the larger size I use is ~$130. But they do support the cable if this is the question.
To tie a generator into your home power system there are 2 ways to do it.
The least expensive is a mechanical interlock kit that locks the main circuit breaker in the off position then allows a breaker to be turned on (yes with the main off) back feeding a breaker from the generator to power circuits that are turned on (some will need to be turned off or you will overload your generator.
The other method transfer switches has 2 sub categories.
A whole house transfer switch is a large “double or triple pole double throw” switch. The utility power is connected on one side and the generator is on the other. The house panel is the common so in 1 position the panel is connected to the utility flip the switch and the panel is connected to the generator )some breakers in the main need to be turned off to prevent overloading the generator.
The second transfer switch method is you choose the circuits to connect to the generator.
Each circuit is a switch that connects single or double pole double throw. These circuits are re-wired to a separate switch box unit that only powers the circuits wanted so you don’t overload the generator each switch is usually moved to the utility or generator position this is the most fool proof but also the most expensive method and it limits what can be powered.
The interlock or transfer switch methods prevent you from back feeding onto the power lines where the voltage man transformed to 12kv up to 35kv depending if in the city or country. That high voltage can kill a lineman or someone messing with down lines that were not hot a second before, but more likely is the massive load on your generator as you just became the power company will overload your generator and hopefully trip it’s breakers if not it will smoke the alternator and your generator is toast.
