Can service entrance cable be spliced?
Also know, can you splice subpanel wire?
Yes, the splice has to be in a junction box, and with this size wire you would probably want to use what is called a "screw cover can"(big box) get one at Home Depot. It has to be accessible. Don''t bother trying to run down crimp on splices and the tool that you are going to have to borrow or rent to crimp them.
Additionally, can you splice in a panelboard? Conductors inside a panelboard shall not fill the wiring space at any cross section to more than 40%, and splices and taps shall not fill the wiring space at any cross section to more than 75%.
Similarly one may ask, can you splice 200 amp wire?
"Splicing" 200 amp service. You can't have "some" available power at that splice point. It will need to be a 100% splice only or you'll need to bring the service cables into a service panel..which would then become your splice point and a sub panel.
What is a service entrance conductor?
Service entrance conductors (aka, "service feed wire") run from the weather-head (exterior point of attachment) from the utility pole to the electric panel (usually the circuit breaker box). For most homes, the service entrance conductor will be located on or near the roof and tie into the overhead electrical lines.
