SIMPush (Sharkbite for EMT)

[billconner]

Just a new thing for me. I guess it could have been predicted. No opinion, just interesting I thought.

Southwire SIMPush 1/2 in. EMT Push Connect Coupling (20-Pack) 65070303 - The Home Depot

20-Pack, SimPush, push-to-install conduit couplings are used to secure 2 ends of EMT conduit together quickly and without tools. These EMT fittings are designed for use in dry locations only. Southwire

A simpler version of the old identer EMT fittings, after the tool was used to lock the fitting on they had to be cut off.

 

[nadogail]

I can imagine that a lot of them will be sold.

Wish I had known about those a few years ago. Used to install security systems and the customer would have liked the needing to cut conduit to undo fittings aspect. A few of the places they required RMC with threaded fittings, they might have accepted these instead for some of the installs.

 

[Mr onetwo]

They make it for all types of conduit. Interested in what Master electricians think about these things? I know how I feel about this stuff in the plumbing/ pipe fitting world.

 

[mike93lx]

Emt fittings are so simple to install though. I get the appeal when a connection is difficult, like dissimilar materials or replacing soldering, but replacing a screw? Seems like a solution in search of a problem

At least they aren't wildly expensive and are only 2x the cost of a normal fitting

 

[cybrdyke]

These have been available for quite a while. They haven't caught on in the electrical world. Too expensive and the existing products are very easy to use. These dont really solve any issues.

PVC, Liquid Tight Flex?

Electricians that drop tools, won't wear tool belts, or maybe are one handed.

Somewhat seriously, it does seem you could go faster, especially long runs of full length pieces. Coupled with some tooless clips, you could run a lot of EMT fast. I wouldnt care, but if I was running a job with 50 electricians and could finish a day or two sooner, lot of bucks.

There was also Sierra Tomic fittings, just press them on.

Those were the originals. I used them in the '70s.
When it was used with sheet metal boxes, the EMT had to be cut so it extended into the boxes.

 

[Crazyjake8493]

These look like a solution for a problem that doesn't exist. EMT is so easy to connect (screwdriver or pliers) - the bending is the "tricky" part for a DIY'er.

I get the appeal of a Sharkbite for plumbing where the alternative is soldering or a press tool. I just don't see who the push-connect EMT fittings are supposed to appeal to. If you don't own a screwdriver or a pair of pliers, you're probably not installing conduit of any kind.

In the USA do you use a lot of threaded steel conduit (EMT ) rather than the bang together fittings. In the sub tropics where I live EMT is used where mechanical protection is needed and stairwells, the Halogen free PVC electrical conduit is used in Railway stations and industry and HD pvc conduit for normal jobs. When I started in the trade it was all steel EMT on the big projects but it changed and the younger guys do not like EMT. A well set out EMT install can look really good. I still have my chain vice and benders and stock and dies and rent them out to other contractors . Regards from Australia.

EMT isn't threaded.
Rigid conduit (GRC) and intermediate metal conduit (IMC) are.

 

[mm08822]

I'm still partial to being able to take things apart and re-assemle without a pile of spent fittings.

That is the downside of glued fittings also - plumbing and electrical.

 

[billconner]

Seems like if you want to add a box in middle of any conduit run it's pretty simple to cut and add without disassembling up to 10' away. And for time and materials to allow somewhat easier disassembly, how often will you really need to do it?

Since this thread was raised from the dead, have some of the Tomic fittings, they do have their place but my days of doing any major projects are over.

Thanks for the clear definition the Rigid steel GRC is what I was raised on ( always referred to as steel or screwed conduit ) so EMT is non threaded using bell joiners. Being a British based country our Electrical standards and voltages and material references are similar with a few difference's to the Brit’s . a friend migrated to the states (for a lady ) and runs a contracting company in NJ and said it took some time to adapt to USA terminology and material differences and your common use of two phase systems, ( 1 phase or 3, 2 phase ended in late 70s and was used for stoves and welders ). regards from Australia

Think of EMT as schedule 10 (1.5 mm wall thickness) galvanized straight tubing. Couplings and connectors are typically set-screw or compression-type ferrules.

GRC is schedule 40.

The 2 phase you referred to in the USA is only single phase, but a split (center-tapped) phase. I does provide for some reduced wiring gauges depending on where in the distribution circuit.

 

[BrandonV]

Wonder how well that maintains a ground compared to a properly tightened EMT fitting.

It’s interesting that we are in the same Industry in different countries that your schedule 10 i have no Idea about nor would you if I said AS:3000 or AS:3008 part 8 2018. Yet if we were on site together we would sort it out quickly. The joys of our trade. We work on a 415 volt / 240 volt system 3 phase /single phase with a multiple/ earth neutral system ( neutral or star point bonded to ground ) a standard residential supply would be 3 x 100 amp per phase conductors the load would be balanced and the 3 phase for voltage drop and Ducted HVAC systems. With your 200 amp supply is it 2 phase 3 wire ? Or 3 phase 4 wire with each phase rated at 200 amps ? Regards

Residential is split phase. 120/240, service is the rating for each 120v leg.

Standard new installs in much of the country is either 200a or 320a, but can vary considerably. I had a house that was 60a, another that was 100a and the current is 320a. I doubt anyone is doing new services at 60, but I would bet 100's still go in somewhere, and the really big houses can exceed 320a or even have three phase. Some parts of the country (thinking Florida) do have residential 3 phase specific to hvac

 

[Norcal]

Two phase is a obsolete system, but still in use in parts of Philadelphia, PA, & Hartford Connecticut, the USA uses single phase 120/240V for residential.

When the other electrician says 200 amp supply ( is that single phase 200 amp or 2 x 100 amp conductors plus neutral coming into the residence? I see the Quicklag circuit breakers are used a lot in the USA ( great product sadly now out of fashion over here, where the leaders for 3 decades ) regards

You get two 100a 120v legs with a neutral. 3 conductors

 

[Norcal]

Each leg is 100A, or 200A one does not add the rating of each pole.

Got it thank you. We direct meter up to 100 amps per phase and over 100amps we use CT metering ( current transformer) which is costly and fault current levels are considered. Regards

100A & 200A have always been self contained meters, it used to be above 200A required CT's, but now there are 400A (320A continuous) self contained single phase meters & are more common for residences, particularly if they will be using electric tankless water heaters which can require up to 3-40A circuits to supply them.
