branch wiring

I am installing 4 new outlets ion an unfinsihed basement on a new fuse. Because of where the panel is located and where i want the outlets, it would be easiest to split the wire before the first fixture and run wires in different directions. In essesence I would create a "t" inside a box joing the wires with wire nuts and running the wires from there. I cant find if that is code compliant.

Welcome to the forums! You can also pigtail two cables going in each direction inside the breaker/fuse panel connecting the pigtail to the fuse block/breaker screw and neutral buss.

You need to have GFCI protection for these receptacles. If the outlets are lights, GFCI protection would not be required.

Yes, you can have the circuit branch off in two different directions from a box with or without a receptacle or switch in it.

You need to be careful to have the box in question large enough for the various wires entering it. If you put a ground fault circuit interrupter receptacle there (it can protect both branches) you should use a box larger than the box fill rules call for since the GFCI unit is larger than an ordinary duplex receptacle.

Quick summary of applicable USA box fill rules: Each hot or neutral conductor, 1 point. All the ground wires, 1 point. All the clamps or fingers inside the box, one point. Short lengths wholly within box (pigtails), 0 points. Wire nuts, 0 points. Each switch or duplex receptacle or single receptacle up to 20 amps, 2 points. For 12 gauge wires, 2-1/4 cubic inches per point, For 14 gauge wires, 2 ci per point.

Example: Two wire feed cable, 2 points. Two 2-wire continuing cables, 4 points. Grounds, 1 points, clamps, 1 point, one receptacle, 2 points, total 10 points. For 20 amp 12 gauge circuit you need a box of at least 22-1/2 ci.
