Should be fine... looks like a 1Kw dimme from the rear and in a bell box that - what’s that has a knockout hole open from the side?
Such dimmers are only rated for wall use, but in a bell box within some spirit of the code in
knock out holes not being knocked in and shorting
etc. Still
wire nuts are never acceptable for use on
portable equipment and I don’t see a
strain relief in use, much less I see some kind of in-line splice within the cable going on within the box - ... interesting work... not normal practice in the box itself not seemingly grounded that’s a bad and against code type of thing amongst stuff like lack of
strain relief for the
cord observed
etc.
Lots of reasons not to use the box presented, but on the other
hand given the
dimmer, this even without
circuit overload protection over it... been there in using them and they do work. Sort of a grey area - in this case I would not though closer than to being within a wall box type 1900 type wall duplex box.
Yep, close to but missing lots of details and in part why one typically rejects such a thing. And what does happen to that electrical box if under multitudes of that box bouncing about as carried up a stair case or dragged along a floor when the
wire nut comes loose and the box touches an energized
circuit?
Someone had an idea but not the spirit of the code or in general concept of
safety in mind in screwing up a good start.
Strain relief? Perhaps not so much afterall.
Reostat,
Variac, Auto-Transormer... This 1Kw
dimmer is better quality but no so much that it does in this instance not qualify as spare parts to be taken apart and not used.
I'm also in further noting this spice the lack of a 6" of
wire out from the tap on both sides of that tap. This in part no doubt due to the in-line splice of the
cord. Hard to do a proper splice if just splitting the
jacket of the cable some, removing some
wire and adding a
wire nut as best possible. Hard to do properly - especially with
wire nuts sinking down to the bottom of your workable area on the cable
jacket in perhaps it got tight or perhaps it bottomed out on the cable
jacket.. .shouldn't be a question - should if properly done be a 6" lead of
wire within the box.
Nothing about how this was done was proper other than perhaps the
dimmer and box choice... after that a world of difference between what is properly and professionally done and something that is hack the
NEC would attempt to save lives in not using by way of rules against the use of. You will no doubt also note a tag on the
dimmer stating something like not other than for in the wall use. Important concept though broken - only broken with care and for special purposes and only than if properly and safely done within the spirit of its use.
Thanks for all the replies. I quite randomly found this "
rheostat" equivalent at work (different
theatre, long story) today.
I'm still not certain what it should be called. This particular one is rated for 1000w, so I should be fine with a 575w S4... right?
