Is this wire attached securely?

[super365]

I am using Panasonic DH-3DL2S Instant Water Heater. After the installer left, I notice there is one metal piece that I think the installer forget to push downwards to secure the wire end, one side of the metal piece is clamping the wire end and the other side facing upwards, see red arrow pointing to metal piece, photo

May I know should I push the metal piece towards the wire to clamp the wire, or leave it alone suppose to be like that? Thanks a lot.

Looks dangerous.

Better get it rectified!

Don't play around with bare wires.

That's the Earth, if the crimping is firm enough, nothing to worry.

Give it a slight pull, if the crimping stay, leave it.

Aiyo. That is a ground cable. Attached to it is a grounding plate. What you can do is just use a long nose plier to clamp it down. It is just a clamp to hold the bare cables.

Its not alarming dangerous. But good if you can just rectify on your own.

Thanks all.

So it is the installer forgot to crimp the other side, sloppy work? Or some people do it like that crimp one side only also can?

I switch off the water heater knob turn to off, then the water heater wall switch turn to off, then use plier crimp it down myself ok correct?

I think the metal plate is installer add it himself, does not comes with the water heater.
Just curious why the installer don't just curl the bronze exposed wire around the screw then screw in?

That one depends...Hard to comment but it's quite true for all.

Yes. Just turn off everything b4 u start the work.

I can't see clearly whether the protruding part is "extra" result from bigger than needed terminal, not an impeccable crimping job, but IMHO, I don't register this as sloppy job if the wire stay with a firm pull.

If you take a good look at those out door Earth wires, they are usually naked without any insulation hence doesn't matter whether the crimping is less than perfect visually, the key point is whether it stay with a firm pull. If it stay, job done, nothing to worry.

his crimp tool sucks, or he use the wrong size to crimp

but hor, I see the ring lug also cheap stuffs, metal so thin

There is a video below the photo showing the protruding part 360 angle view.

I missed the video link earlier.

Look like extra from a bigger than needed terminal for the Earth wire. Look rather firm to me, the terminal is not those split end type so any extra from the crimped cylinder will end up as a flap at the side.

If I'm in your shoe, I will leave it there and not bother about it. But if you're not comfortable with it, ask them to redo the terminal for a peace of mind.

Not possible for installer to come again because installed a few months ago.

This earth/ground wire if it loosen by itself and then happen to touch any other parts of the heater will it cause any problem?

I think I will check again and if not secure I will clamp it down using long nose plier.
