Multi circuit wiring ? - Outlet

Not sure if the subject title is correct, but here's my situation.

New addition with 2 branch circuits. Service to addition is by way of 4 wire Romex. (White/Red/Black/Ground) Two separate circuit breakers in main service.

Electrician wired the circuits and set up each box for recepticles/switchs Pretty straight forward stuff.

My question. The outlet box where the supply wire comes in has the following wires:

4 wire Romex in.
(2) 3 wire romex out - circuits (a) and (b)
1 loose red wire from supply
Black from supply and circuit (a) tied together
Black to circuit (b) loose
All (3)white wires loose (?)
All ground tied together with 1 jumper loose.

What is the correct method to wire this to the single duplex outlet, and the remainder of circuit (b)?

What's throwing me off is all the white wires loose. How do I attach these?

Thanks in advance.

 

I agree with the answer you got at Handymanwire.

 

And what answer would that be?

It appears that the thread was deleted before I could read it.

14/3 cable from panel to a receptacle outlet box.The 14/3 cable powers two 15 amp Branch-Circuits.There are two 14/2 "feed-out" cables in the receptacle outlet box for a total of 7 Branch-Circuit conductors and 3 Ground conductors in the box.------The 3 Ground conductors AND a Ground lead that connects to the receptacle Ground terminal are bonded together with an approved bonding connector such as a crimp sleeve.-------The 3 White Branch-Circuit conductors AND a White lead that connects to the Neutral recptacle terminal are Wire-Nutted together-------The Red BC conductor of the 14/3 cable WN's to the Black BC conductor of one of the 14/2 "feed-out" cables.-----The Black BC conductor of the 14/3 cable AND the Black of the other 14/2 "feed-out" cable AND a Black lead that connects to the "live" receptacle terminal WN together.-----Finis----Good Luck!!!

Your explanation made complete sense, and is what I did.

I still have some ceiling fans and exterior lights and receptacles to install before I power up. I'll let you know how it turns out.

Thanks for the help.

Just wanted to let you know that I wired per your instructions, and powered up the new addition.

Everything works and all receptacles have proper polarity and ground.

Thanks for the advice.
