2011年11月13日 · So, I'm planning a 50amp feeder breaker in the main panel with #6 feeder wire to the sub-panel. But, the local retail stores don't carry (Siemens) panels smaller than 100amp. I checked with the local inspector (Seattle) and he said that it's common practice to feed a larger sub-panel (e.g., 100amp) from a smaller main feeder breaker/wire (e.g ...

2009年9月12日 · 334.14(C) In Unfinished Basements. Where the cable is run at angles with joists in unfinished basements, it shall be permissible to secure cables not smaller than two 6 AWG or three 8 AWG conductors directly to the lower edges of the joists. Smaller cables shall be run either through bored holes in joists or on running boards.

2007年10月31日 · A5. If the hot tub is located indoors, then NM cable can be use as the wiring method [680.43]. However, if the hot tub is located outdoors of a one-family dwelling, then NM cable can be for the indoor portion [680.42(C)]. Outdoors, the most practical wiring method will be rigid nonmetallic conduit and liquid-tight flexible conduit [680.42 and ...

2010年4月26日 · If I'm reading the NEC table correctly, 3/4" PVC conduit can have up to (3) 6 AWG conductors. Does this mean that no other conductors can be present, or can I also have a 10 AWG grounding conductor in the conduit?

2008年11月23日 · The NEC (300.14) requires at least 6" of free conductor, measured from the point where the conductor emerges from the cable sheath or raceway, and also the conductors must extend at least 3" from the opening in the box, if any dimension of the opening is less than 8". Note that the 6" is not measured from the front of the box.

2014年11月30日 · Hi all, We just purchased a hot tub and are now waiting for it to come in and planning out the electrical. We currently have a 200a main panel. In that there's a 50a/double pole breaker feeding a subpanel directly underneath it with #6 AWG wire. The subpanel has a 60a transfer switch in it (not...

Nov 6, 2010 #3 And with 80' of a #10 AWG copper conductor and a 6900 W/240 V = 29 A draw, if you see more than a 2.3 volt drop in the 240 vac measured at the oven when you turn it on there is a bad connection somewhere.

2014年5月3日 · #6 Every time you add a connector, you have an added resistance - it would probably work fine, but initially monitory things and see if the connector or wire gets hot. Some power supplies have overload protection built-into them, so while a fuse never hurts, it may or may not add much to the overall safety of the installation.

2008年4月18日 · We bought a new upright freezer. With where we're wanting to put it, we need to use an extension cord. The maintenance man who works at my wife's workplace told her that using an extension cord for our freezer would mess up the motor.:confused: That makes no sense to me, is there anything...

2019年3月20日 · PVC conduit is very low cost and offers excellent protection. If it is a short run, say 20 ft then just bury the UF. If you don't use conduit, you need to protect the UF in schedule 80 conduit or metal conduit to protect the UF cable going vertical. After trenching you'll need at some locations for the wire to be seen at the 24" dept.
