question about making a junction connection inside a service entrance panel

question about making a junction connection inside a service entrance panel

I am installing a securty light and outdoor receptacle, and I want to connect these two things to a 20-amp circuit that supplies power to a light and recptacle in an outside storage building. This is a mobile home so the service panel is outside the home. My question is: Could i terminate my new circuit inside the service entrance panel , connect my neutral and ground to the neutral/ground bar and splice into tje existing 20-amp feed using a wire-nut connecting the two feeds plus a pigtail going to the twenty amp breaker. I am asking this because i do not have a rainproof junction box to use to make these connections outside the service panel.

Some circuit breakers let you place 2 wires
under the terminal. Check thet first.

By the NEC you are not allowed to junction inside the panel. On most occasions your lug of the breaker is not allowed but only one wire under that lug. But it is commonly done everyday. If you are going to cheat I would rather see the two wires under the lug of the breaker than the junction with a wire nut in the panel. Although neither is legal and approved.

Good Luck

Square D panels, at least the HomeLine models, have single breakers with two lugs. I don't use 'em, but they're listed, so it must be OK, right?

Another alternative is to buy a "tandem" breaker. It fits in a single space, but consists of two separate breakers with two separate handles. Most panel manufacturers make these for their brand panels. This is particularly handy if your panel is full. If you go this route be sure to bring your panel make and model info to the store with you.
