Any non-flexible metal conduit that goes back to the same panel (at a junction box).any other point with a large enough ground going back to the same panel.The ground wire can be bare, and routed independently from the other wires.The ground wire must be #14 for a 15A circuit, #12 for 20A, and #10 for 30-60A.(You are not allowed to do that for any other kind of wire, for very good reasons but grounds only carry current during fault conditions). If you don't actually connect any surface conduit to it, I won't tell :) Retrofit ground, insteadĪs of NEC 2014, which California adopted, you are allowed to retrofit just a ground wire. You can buy yourself some additional space in a too-small box with a surface conduit starter box, which sits about 1" proud of the wall surface. If both cables come from the same direction, you can move the box that direction and regain some critical length.
The wires in that box are entirely too short - they must stick out at least 3" beyond the wall surface and 6" of length past the clamp. Note that if you're changing the box, you should consider moving the box too.
#HANDY BOX ELECTRICAL CODE#
It's not Code legal to try to cram an AC cable into a plastic box intended for NM, and that won't ground anyway! Metal boxes can be had with either knockouts or internal cable clamps, or both. Also, plastic boxes are incapable of providing standard knockouts, and many older wiring schemes depend on them. Stay with metal, not least for fire resistance (better heat dissipation) but also because some older grounding schemes depend on them. While the old "handy-boxes" were small and sized for their time, modern joists-and-drywall metal boxes are perfectly large.
A bigger boxĭon't downgrade from a metal box to a plastic one. If it is a kitchen or bathroom outlet, you can use a GFCI deadfront near the panel.
#HANDY BOX ELECTRICAL INSTALL#
If it's it's not a kitchen or bathroom outlet, you can install a GFCI receptacle somewhere, and route the circuit via that point. You can use a GFCI breaker if they're made for your panel. Install it elsewhereīecause of the above, if a GFCI will not physically fit, then you have the option of installing the GFCI protection somewhere else. *Connecting them nose-to-tail, elephant style, is playing a "Yo Dawg" trick on yourself! It will drive you crazy if you ever trip one of them, because they'll all trip, and they won't reset except in a particular sequence. Because of this, putting two GFCIs on a circuit is usually wasteful. GFCIs simply look for differences in hot and neutral current they don't even need ground for that. +Quick Delivery: 20days for one 20ft container.All GFCI devices are able to protect portions of a circuit downline. Extension rings are available to provide a means of adding additional wire capacity or to serve as outlet boxes for surface conduits.įield Names: Handy box, utility box, 2x4 box, switch box,device box, handy box extension ring, utility box They are great for appliances and machinery.
These handy utility boxes are used for convenience outlets, switches and small junction boxes in exposed work applications. TOPELE 4 ” x2 ” Electrical Conduit Handy Box 0.6mm, 0.8mm Thickness 4”X2” Square / Octagonal Handy Box, Electrical Boxes And Covers
