    Using a surface box differently

    An electrician installed a NEMA 6-20 20A 230V outlet in a surface box for me in my garage, on a dedicated 20A breaker. He was even kind enough to follow code and run a neutral wire: I would like to replace this outlet with a side-by-side single 6-20 and 5-15 duplex so the box can be used for...

    Attractive Covering For Ceiling Box - USA

    Thank you for the tip about commercial box covers. I found plastic and metal ones at HomeDepot. They're not so pretty, but may be the best choice. Attached is a picture of the box and the surrounding drywall. Unfortunately, the drywall edge is a bit rough around the box.

    Attractive Covering For Ceiling Box - USA

    I just installed can lights in the ceiling, replacing a hanging light. That leaves me with a live 4" round box in the ceiling. Code won't allow me to conceal it or mud over it. The ceiling is drywall with hand-troweled ripples. What can I do to cover this live box that will look nearly...

    Spa bath with lights

    If possible, contact the Spa maker for advice. If the connection exists, it is required by code that it be correctly wired. It is also definitely safety-related, so don't ignore it. My guess is that the extra earth connection is there in case something goes wrong with the pump. You do not...

    DC activated AC relay

    There are relays with DC coils that are rated for AC switching. The keys are the load voltage and current (240VAC at 15A or something like that). Then you specify one with the right coil voltage. For example, TE Connectivity Potter & Brumfield makes a few like that. Digikey.com is a...

    Unsecured jbox in attic - USA

    I bought a new house in Florida in 2022. Today, I went into the attic. I found wiring stapled to studs in a few places, but there are no guard strips. I also found a connection box laying on a joist/truss, dangling from non-metallic cable (Romex). See photo. This attic is not occupied, has...

    USA Lamp cord / Zip cord - permanent installation

    I bought an under-cabinet light fixture. It is LED, so low power (120VAC 12.5W). It came with a detachable SPT-1 power cord. One end of the cord plugs into the fixture. The other end is a NEMA 1-15P two-wire plug. Here are the installation instructions that came with it: I heard that NEC...

    Hanging a "flush mount" light by a chain?

    Megawatt, Thanks. That's certainly how the manufacturer intended it. But that's not what I want to do. Perhaps you're telling me politely to do it right and I'm too thick to understand. :-) I'm thinking of doing something like shown in the sketch below. It would require connecting two boxes...

    Hanging a "flush mount" light by a chain?

    Wouldn't it need to attach to a code-approved metal box that is engineered for chain hanging? I'm trying to find that sort of box.

    Hanging a "flush mount" light by a chain?

    I have a light fixture that is intended to be flush mounted to a ceiling box. I would like to hang it from a chain so it is 2 feet down from the ceiling. Here's a photo of the fixture mounting plate and wires. (USA mainland, ETL/UL standards). Is there a correct way to do this, such as a...

    Push-in connectors on Leviton outlets

    Thank you. Yes, I can do that. I'm pretty confident in my abilities with a quality wire nut. Strange: When I search one of the big-box store's website for Wago, they show Ideal "In-Sure" push-in connectors, which seem like the same stab concept. They may be better than the Leviton stab...

    Push-in connectors on Leviton outlets

    The electricians who wired my new house (US mainland) used the push-in connections on the back of Leviton budget outlets rather than the screw terminals. I've already had two wiggle loose making the outlets intermittent. They are UL listed outlets, so theoretically, they have been tested for...

    USA Ceiling Fan Box is Strange

    That's it. Thank you. I found a catalog page on the web. I'm not sure if this includes a hot link or not: "MANUFACTURER CATALOG DOCUMENT". https://www.shopeeco.com/2461813/Product/Arlington-FB443 It looks like the fan bracket would screw into the stud behind the box, not the box. That is what...

    USA Ceiling Fan Box is Strange

    New construction in USA. I think that the builder put ceiling fan rated boxes in the ceiling. But when I remove the cover, I see a strange box. Picture attached. It's hard to make out all of the details, because the painter sprayed it. Have you seen this brand/style box before? There are two...

    High frequency lighting with low frequency fittings

    We're going to need some more information to be certain, but if the bulbs are basically the same type, you should be fine with the new bulb. We know that 50Hz or 60Hz means the power mains frequency. I believe (but can't be certain from afar) that 20kHz means the switching frequency of the...

    Unimaginable amount of electrical noise after plugging PC Power Supply

    There is a high probability that the PC power supply is defective. Can you take the PC and noise meter to a friends, just to rule out your particular house's wiring & supply issues?

    Are these boxes overfull? (USA NEC 2017)

    I just redid the math using what I think is correct, for what I think is going on. From the two photos, it appears that this box has 4 gray cables, 3 yellow cables, & 1 white cable. Yellow is commonly 12-2+G and white is commonly 14-2+G. Gray is underground cable, with nonspecific gauge...
