Hi I Was Wondering If Anyone Could Help Me Out Can SER cable Be Direct Buried On A Temp. Service

Re: ser cable

No, type USE would be the correct choice.

Re: ser cable

Can it be? Sure..all it takes is a shovel

Would it be code compliant?
NO

Type SE. Service-entrance cable having a flame-retardant, moisture-resistant covering.
Type USE. Service-entrance cable, identified for underground use, having a moisture-resistant covering, but not required to have a flame-retardant covering

Have I ever seen an inspector allow it (buried) on a temp service? Yes

Re: ser cable

From the UL White Book:

Type SE ? Indicates cable for aboveground installation. Both the individual insulated conductors and the outer jacket or finish of Type SE are suitable for use where exposed to sun.

Types USE and USE-2 ? Indicates cable for underground installation including direct burial in the earth. Cable in sizes 4/0 AWG and smaller and having all conductors insulated is suitable for all of the underground uses for which Type UF cable is permitted by the NEC. Types USE and USE-2 are not suitable for use in premises or aboveground except to terminate at the service equipment or metering equipment. Both the insulation and the outer covering, when used, on single and multiconductor Types USE and USE-2, are suitable for use where exposed to sun.

Well we got type ser and use, but does anybody know what designation type seu is? Is it the same as use?

No, SEU is in the "SE" category. It's not suitable for direct burial.

SEU is service entrance concentric and SER is service entrance round.

Re: ser cable

Correct me if I am wrong but isn`t SE 2 hots with a braided grounding conductor and SER has 2 hots 1 grounded conductor and a seperate grounding conductor(uninsulated)
Terminology can get somewhat confusing.Such as go to a supply house in nyc and ask for a 4 sq. they look at you like you have 2 heads but ask for a 1900 and blam on the counter is a 4 sq.
Also ampacity changes from se to nm #6 se is rated for 60 amps but #6 nm isn`t.yeah I know it`s about degree table listing

SER as Pete pointed out is R for round.

SER may have 2 or 3 hots, along with an insulated Neutral and the bare grounding conductor.

We use a lot of 4/0-4 AL SER for temp 3 phase feeders.

SE is flat and only has two insulated and one bare conductor.

SE is not useful for much other than a service or loads that do not require a neutral.
