Shore power question

[callistov42]

I want to relocate one of my two shore power inlets about 18" and install Smart Plugs.
Of course there is not that much slack in the wiring so I need to extend my boat side wiring. What is the correct "marine" process? With 12v I would use butt connectors and shrink tubing. Is it the same for the bigger 30amp romex cable?

The correct process is to use a new cable from inlet to breaker, which should only be a very short section if following recommendations

That is too important a run to butt splice. Remember, the over current protection is a, generally flakey, pedestal circuit breaker that is protecting 50' of shore power cord and, if built to spec, 10' of onboard cable to the first onboard circuit breaker.
