splicing wire

question, i am wiring an outdoor security light and have 10 gauge coming from the breaker but i do not have enough to make the distance i need. i do have some 12 gauge wire and so i am wondering if i can splice the two for the remaining distance i need?

Depends on the breaker size. If it is 20 amp yes. Why did you run #10?

What are you doing.... wiring a single light or an entire parking lot ?

You need #14 wire on a 15A circuit breaker.

actually he started to run the 10 to a shed and also run a pool pump and small hot tub. He was going to tie into the 30 amp with 10 to also run the light. I do have some 12 gauge, would it be better to run it separately for the light to another smaller breaker?

I would definitely use the smaller wire on a smaller breaker. #12 on a 20A circuit breaker is much easier to work with.

okay i was hoping to just use a little bit of 12 gauge to make up the short distance i needed to the light. But it is probably better for me to just run the 12 and pick up a 20 amp breaker for it. Thank you.

A 30 amp circuit cannot be used for general purpose lighting and receptacles, 20 amp max.
