What is the difference between SE and Ser cable?
Style SEU cable has two phase conductors surrounded by a concentric neutral while the SER style has two, three or four phase conductors and a bare neutral.”
Where can se cable be used?
Type SE cable is often used for interior wiring to supply heating and cooling equipment, appliance branch circuits and for feeders to subpanels.
Does SE cable have to be in conduit?
SE cables simply can’t be buried, conduit or no conduit.
What is SER cable rated for?
600V
SE cable is rated for 600V not to exceed 90C in wet or dry locations. Single conductors are UL Listed Types XHHW/XHHW-2. The cable is rated sunlight resistant.
What is #1 Ser rated for?
SER is type SE, Style R cable, used as an above ground service entrance cable, a panel feeder and in branch circuits. The cable is rated at 600 volts and 90_C for use in wet and dry locations….Product Details.

Can you put SE cable in conduit?
Can you run se cable outside?
SE cable also cannot be used for exterior branch circuit or feeder wiring, unless the installation complies with the provisions of Part I of Article 225 and is properly supported. USE shall not be used for interior wiring at all since it does not have a flame-retardant covering.
Can you run se cable underground?
SE cables simply can’t be buried, conduit or no conduit Why you’re seeing “SER can’t be buried” on this site is because the rule’s right there in section 338.12(A) of the National Electrical Code (irrelevant point 1 snipped): 338.12 Uses Not Permitted. (A) Service-Entrance Cable.
Is Ser cable rated for conduit?
Buried cable, in or out of conduit, must be rated for “wet location”. That’s the problem with SER, it’s not rated for “wet”. Regardless of what your friend did, use the correct cable. His installation is incorrect in spite of being “advised” by an “electrician”.
What size Ser cable do I need for 100 amp service?
For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire.
What is ampacity of wire?
Wire Size & Amp Ratings Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
How can I determine the ampacity of conductors in Conduit?
Please consult a qualified electrician or professional engineer to determine the appropriate values for your specific application. Our new Ampacity Calculator app can help determine the ampacity of conductors in conduit, cable, or directly buried wires. Cerrowire markets through a number of quality retailers and manufacturer’s representatives.
What is the meaning of ampacity?
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps”.
What determines the ampacity of an electrical circuit?
The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Usually, a general-purpose house circuit is designed for 20 amps. Lighting circuits may be designed for only 15 amps.
