2017年7月26日 · The screw on the underside of the tool clamps the armor in place. The crank handle turns a little circular metal cutting saw blade that cuts the spiral. There is a set screw that adjusts to limit the depth of cut. You squeeze the handle to press the wheel down, crank, and stop when you get through the high part of the spiral strip.

2019年10月5日 · The right solution is to add a ground wire to the inside of that conduit the entire run. The answer is to reroute that EMT and flexible conduit so it uses a different path. Don't be bashful about getting more EMT or flexible conduit to extend. They sell pre-bent sections and they also have conduit benders. Do not exit the conduit with bare wires.

2024年6月7日 · Electrical Nonmetallic Tubing (ENT), is designed to replace EMT, flexible metal conduit or other raceway or cable systems, for installation in accordance with Article 362 of the National Electrical Code, other applicable sections of the Code, and local codes. On page 3 it notes that the (smurfy) blue color is their registered trademark.

2024年5月2日 · Someone has added flexible metal conduit at several junction boxes down line that includes a ground wire in them. I'd hate to just leave unconnected ground wires floating in each of these boxes and want to confirm that I can attach them to the metal j boxes without running a new wire all the way back to the main panel (assuming that the conduit ...

2023年11月19日 · I’m looking to run 3 circuits 20A 120VAC (3 wires per circuit; H,N,& G, 12 gauge THHN) together through 3/4” FMC. Circuits will have ground fault and arc protection breakers. Residential baseme...

2015年6月23日 · a. The conduit is terminated in listed fittings. b. The circuit conductors contained in the conduit are protected by overcurrent devices rated at 20 amperes or less. c. The combined length of flexible metal conduit and flexible metallic tubing and liquidtight flexible metal conduit in the same ground return path does not exceed 1.8 m (6 ft).

2021年8月3日 · I can't find a specific answer for this situation. I know that flexible conduit can be used as a 6 foot whip for luminary and "other equipment". It can be used over 6 feet. The question that I can't seem to answer is if a whip exceeds 6 feet and needs supported every 4.5 foot span, does that include the support of the 6 foot whip.

2023年10月7日 · The existing circuit is wired from the main panel into a metal junction box using 2-strand ROMEX (without ground wire), the hot wire is tied to a ROMEX feed that exits the junction to a switch in another room, then the return from the switch is wired to THHN wire that feeds through the metal conduit to the elbow at the exterior of the home (one ...

2019年9月14日 · Flexible Metal Conduit. This is empty conduit (a pipe) in which you add your own wires. The metal shell of FMC can be used as a grounding path provided it is less than 6 feet and terminated into metal boxes with cable clamps listed for FMC. But I …

2023年6月5日 · That is more work overall, though you get to use much smaller conduit (1/2" PVC 80 or RMC will work just fine). Running NM cable through conduit is not easy in general. In fact, based on everything I have read, liquid-tight is the hardest type of conduit to run wires or cable through, so this would be a double problem.
