Charger installation - best way to adpat knockout to 3/4" conduit

[regazzoni]

I am in the process of installing my wall charger. I am using the bracket for top feed with conduit. I am running 3/4" conduit. The top knockout is meant for 1" conduit. Typically, I woudl be using a reducing washer. Just wondering what others are using given the plastic shell.

I used a reducing washer/bushing on the last install. Just be gentle with it and it should be fine.

There is a YouTube Tesla wall connector installation video where there were detailed specifics on this using a Rigid Pipe part. Look at 19m55s time index.

I couldn’t find the part at my local hardware stores and ended up using 1” EMT and that worked great for me.

thanks.

BTW. Does anyone know the name of type of screw used to mount extended profile bracket? The screws are to short when going into drywall.

P.S. isn't that a metal screw anyhow?

I used 3/4” PVC conduit for my short run, found an adapter that mated up nicely with the HPWC. It took some digging through my local hardware store, but I succeeded.

For those in conduit code areas...

After some more investigating, it seems there is simply no perfect solution. Especially, if you desire you make a watertight connection

Here is what I tried:
1.) using reducing washer

problems: a.) second washer does not fit inside. b.) watertight EMT connector threads are not long enough to receive lock nut.
There is a product with longer thread, but only available in 25 packs... (3/4" Raintight Compression Connector with Extra Long Threads)​

2.) using a 1" rigid connector with 1" to 3/4" reducer bushing and then 3/4" water tight EMT compression.

problem: not really watertight​

What's preventing just using 1" EMT?
