How To Ground Old Two-Wire Outlets
Can I run a line from the panel to one location then bring all of the grounds from the outlets on one circuit to that location and tie them all together there, or do I have to run the ground to each outlet and splice each one in there?

Installing Ground Wiring for Old 2-Wire Outlets
I am running ground to outlets in an older house with only black and white wires. I have been told that I need to run one “home run” ground from each circuit.
I have run one ground wire from the receptacle box to the crawl space under the house. I have left a lot of slack on the wires and would like to bring each one from the circuit to one location rather than splice each one in. I intended to make the connections inside a plastic one gang box. Is this acceptable per code?

Grounding Old 2-Wire Outlets
Ryan, as long as the ground wires will be spliced together and the junction box has the cubic inch capacity for all the wires then this should be OK. The concern is to bond the new ground wires together but not exceed the box-fill capacity.
