2-2-2-4 Aluminum SER Service Entrance Cable

2-2-2-4 Aluminum SER Service Entrance Cable .....
Can I use this cable for dedicated 30 amp 175' run from my home service panel to an RV?

Maybe although it would be overkill and a waste. What is the voltage you need; 120 volt, 240 volt or 120/240 volt. How were you planning on installing the cable? SER cable needs to be supported and isn't intended for direct burial or aerial applications.

Only need 120 volt....I may go with a 50 amp breaker. My current RV takes 30 amp. Option of using this cable in conduit? Just looking for cheapest way to make a run of 175', 80 feet inside/ basement, and about 100' outside buried in conduit.

I could put in 2 pole 50 amp for future 120/240 use.

SER cannot be used underground, even if in conduit.

If the RV receptacle is rated at 30 amps, the breaker cannot exceed 30 amps. You cannot use a 50 amp 2 pole breaker without setting up a subpanel and feeding the RV receptacle with a 30 amp single pole breaker from the subpanel.

Yeah. I am going to do a 30 amp now...a 50 if I get a different RV down the road. Just planning on what type of wire. May have to go with a UF 6/3...although more expensive. Just seeing if there are direct cheaper options. Maybe SEC inside and direct bury or type that can conduit outside. Big price difference between 6 gauge UF and SEC.

Individual conductors are much easier to pull in conduit than a cable.

And individual conductors should be cheaper than a 6-3 UF Cable too.

Is SER 2-2-2-4 inside ok then junction to....
" Southwire’s Quadruplex URD used for secondary distribution and underground service. It can be used for direct burial or in ducts." ....2-2-2-4
from Homedepot for outside. A lot cheaper than a 6/3 UF route. Will a 2 gauge fit into a square d breaker direct? or just put into sub-panel first?

You are going to need a panel at the studio and a grounding system.

liking the Single conductor idea...could go with 4 or 6 gauge?....would you pull 4 wires for future 50 amp 120v...or get away with 3 and use neutral as the ground?

That would work. The junction box will have to be a NEMA 3R raintight.

Probably not. You may have to splice to a smaller wire size at each end.

I'm thinking about a 50amp breaker in my main panel...then running single pole wires.. then a 30 amp breaker at sub panel to plug. In future can just replace 30 with 50 or wire direct to the plug.

Run 2-2-2-4 SER on 60A breaker from inside panel to outside junction box.

Transition from SER to URD in outside junction box.

Run URD sleeved in 1.5'' conduit until 24'' underground.

Direct bury URD until coming up inside conduit into panel.

Install 6 or 8 circuit outdoor panel OR a RV pedestal.


Example of pedestal: GE RV Lighted Earth Buried Pedastal 100A 120/240V Unmetered with 50 Amp, 30 Amp, 20 Amp GCFI Circuit Protected Receptacles-GE1LU532ESL at The Home Depot
