Has anyone seen an SE Cable Style U with no red line?


We tried to install our oven yesterday and discovered that both hot wires are solid black. Does anyone know how we can tell which one should have the red line?

Doesn't matter, both are hot.

So if we're connecting them to the oven, they're interchangeable? The instructions said to connect the red one to the right side and the black one to the left side.

Each maufacturer colors their cable a little different... your stove/oven just assumed one hot was black, one was red (traditional marking). As long as you've got both hots, right or left doesn't matter

If you installed an SE cable for your oven, you have created a code violation and should install the correct cable. If the SE cable was already present, you do not need to replace it.

Is your oven straight 240 volt and not 120/240? If it is 120/240 you may have the issues JV brought up above.

Jim and JV... Could you explain further.... I've never really understood the difference and application of :

1) The differnce in SE (r) and SE (u) for service entry

2) And why you don't / shouldn't use SE for an appliance run (apart from being aluminum)

Don't both SER and SEU come with the different current carring conductors and ground wire in most all sizes and necessary configurations.

Thanks for any help understanding

Peter

SE-U is two insulated condcutors with a third spiral wrapped conductor. It is normally used for servicee entrance cable. Normally the bare is used for the neutral in a service application.

SE-R has three or more insulated conductors and a bare grounding conductor. Two hots, a neutral and a ground. A stove with both 120 and 240 volt requirements could use Se-R. Se-R would also be used to supply a subpanel.

Both cables can be aluminum or copper.

This is an existing power supply and we haven't moved or extended it.

This is what it says for electrical requirements:
Power Supply Connection Location: Rear Bottom Left
Connected Load (kW Rating) @ 240/208 Volts: 13.7/11.3
Voltage Rating: 240V/208V/60Hz
Amps: 57.1/54.3
Minimum Circuit Required (Amps): 50

Now we're worried because the circuit it's on is a tandem 40 amp (each of the small breakers says 40). We aren't sure if that means it's 80 amps total or 40 and the range requires 50, so I think we might be calling a pro in.

You need to determine what wire size the SE cable contains, and if it is copper or aluminum.

The 40 on the breaker is a 40 amp circuit. You do not add the handles to get an 80.

Your current breaker is too small according to the requirements posted.

Do not change the breaker without knowing the wire size and ampacity.

Thanks everyone. I think this is going to be more advanced than what we're comfortable taking on ourselves, so I'm going to bring in an electrician. I really appreciate the help though!
