![]() ![]() I realize existing installations are subject to the code at the time of install, but I doubt the 10 was ever legal with grounding raceway. The exception allows the metal box to be connected to the neutral, but the section doesn't specify grounding metal raceway, ostensibly since then an equipment ground is present. You could run a ground wire from the panel through the dryer outlet box, but then you no longer satisfy the NEMA 10 exception which specifies "where an equipment grounding conductor is not present", so you would have to replace your dryer receptacle and cord with a safer NEMA 14.įrom your description in the comments to other answer I don't think your NEMA 10 is legal at all. If a current happened to make its way onto. If you just even had the compressor plugged in you would be exposing dryer current to the compressor ground. 3-prong dryer cords contain two hot wires along with a third wire that contained both the ground and neutral wire. No you can't legally tap wire for wire from the receptacle, the NEMA 6 is two hots and a ground, NEMA 10 is two hots and a neutral that by special exception allows grounding via the neutral conductor (NEC 250.140 exception). It'll be much easier to run the conductors from a new receptacle directly into the breaker box and make the junction there. ![]() The two-receptacles-one-breaker arrangement could be accomplished by putting the junction in the box with the dryer outlet but it might violate box fill rules and definitely would be crowded and hard to work with. The terminal on your breaker might be designed for landing two conductors, but if not, attach a pigtail of wire to the breaker and use a wire nut to join the pigtail with the leads going to the two receptacles (times two: this same arrangement for both poles of the breaker). If the panel has no room for a new breaker and you don't want to replace existing breakers with a quad breaker solution, you could choose to feed both receptacles from the one existing breaker. I believe code allows multiple 30A receptacles to be fed from a 30A breaker. Since the panel is just right there, get a bit of conduit and a box and install a new L6-30R receptacle. Keep this number handy youll need it when shopping for your converter. If the number you found is already in watts, there is no need to multiply it. It would deal with the ground-vs-neutral situation correctly. Multiply a measurement given in amperes by the machines voltage (220V). How To Change A 4 G Dryer Cord And Plug 3 Dengarden. How To Install 3 And 4 Wire 240 Volt Dryer Cords Fred S Appliance Academy. Ge 6 Ft 3 G 30 Amp Dryer Cord Wx09x10004. If you upgrade to a 14-30R then you could easily make or buy an adapter from the 14-30P to L6-30R. Wiring 30a 240v Outlet For Dryer Electrical Technology Facebook. Sometimes, ground is present, but someone has downgraded the socket from NEMA 14 to NEMA 10 because the buyer complains that it deoesn't match their 3-prong dryer plug. This is an upgrade that is just good sense to implement. First, open up the dryer receptacle junction box and see if a proper ground wire (distinct from the neutral wire) is hiding back there. Given the proximity of the 10-30R receptacle to the panel, and the presence of conduit connecting the two, you could upgrade the 10-30R to a 14-30R and likewise swap out the power cord on the dryer. ![]()
