Non-GFCI and GFCI outlets in the same receptacle

Factual Questions
1

I have a treadmill that needs to be plugged in to a standard (non-GFCI) receptacle. It’s in the basement, so other receptacles should be GFCI. Can I safely put one of each in a 2-gang box?

That is, can I bring the black (hot) wire to the brass screw on the regular receptacle, then put a black wire from the other brass screw to the LINE screw on the GFCI, and the white (neutral) wire to the silver terminal on the regular outlet then put a white wire from the other silver screw to the silver LINE terminal of the GCFI outlet, and finally, pigtail a bare wire from the two green terminals to the bare (ground) wire in the cable?

If it makes a difference, it’s a plastic box and I’d label the heck out of each outlet (protected/not protected).

This would have a non-protected receptacle to plug the treadmill in to, and a protected outlet to plug in anything else that comes along (and I won’t be going through all this wiring for one outlet).

Thanks,

Rhythm

I am not an electrician and it sounds like it would be better for you to talk to one about this. I can say that your description is how I would handle the situation. With the understanding the the regular outlet is not protected by the GFI.

Is the basement finished? If so check your local codes. Usually the finished part of a basement doesn’t require GFCI outlets.

The basement is unfinished, which is why GCFIs got stuck in my head in the first place.

My main hope is not burning the house with my wiring. I’d like to do it as code-like as possible.

Short answer yes.

Longer answer as mentioned in the other thread a non-gfci is permitted in a basement in if it is a dedicated outlet. ei not a convenience outlet. Having one of each in the same box gets into a gray area. Some inspectors might say no to such a configuration.

Moving forward I’ll assume either it will never be inspected or the inspector does not object.

Your wiring plan is correct. Hit the non-protected outlet with both wires first then go to the line side of the gfi. Any further wiring you want protected would come off the load side of the gfi.

For the dedicated circuit you need to use a single receptacle not a duplex.

Thanks!

Again, my concern is more for the not-burning aspect of things more so than the passing inspection. I realize there is more of an overlap than most people give credit for, and if the occasion for an inspection ever comes up I’ll probably volunteer it to ask if it’s okay (I’d hate for something to happen to the next owner).

But in the meantime, if I’m going through the minor hassle of installing a circuit, I’d like to get the most use out of it. In doing so, I was hoping not to do anything particularly dumb. Fire hazard? Health/electrical hazard? Sounds like we’re okay on those fronts, and clearly marking things for future reference is a step towards prudence. Of course, if I’m over-reading anything, let me know!

Thanks for the check!

Now, all we have to do is start using the treadmill. One step at a time, I guess. (literally)

it is not a good idea to dasie chain outlers. You need to make a splice and run wires to each outlet. If you do not know how to do this safely call an pro.

It sounds like you’re adding a new circuit for the treadmill. In that case, I would use a dedicated, unprotected outlet. If you also want GFCI-protected outlets, run an additional circuit for them. I don’t like mixing them on the same circuit because you end up with it not being clear which outlets are protected and which aren’t. You can label the heck out of them, but someone will replace the outlet covers someday and the labels will be gone.

My rule is - if a circuit has a GFCI outlet anywhere, the entire circuit must be GFCI-protected. This is usually accomplished by putting the GFCI outlet first and having it protect the outlets downstream. I never install a non-GFCI-protected outlet before a GFCI-protected outlet.
