I have an electric shower head water heater. If you only have a cold water feed, it’s a great gizmo to have. The problem has been the proper current to operate it. It says it requires 110V 4800W 50A 50/60HZ

I installed it directly to my wall plug in bathroom. First it tripped my breakers. I stopped using it. The electrical wall plug felt hot too.

So, now I’m wondering what I have to do to use this thing. Is there like a mechanism, like converter or current stabilizer, that I could plug the shower head into instead of plugging it to the wall?

Running a separate cable directly to to my breakers is not an option. Also just installing a bigger breaker doesn’t seem like a good option either because my wall plug unit got hot.

Is there a product that could help me?

Thanks,

Vic

I am adding photos to clarify my issue. I would like an option to NOT having to run cable directly to box. I do admit it doesn’t seem likely that I have any option.

    Heating water takes a lot of energy, and if you are in the USA, our 120v power generally isn't up to the task for these instant point of use heaters unless a specific high-current circuit is run. Even if there was a device to cut the power usage of the heater, it would no longer heat the water (very much).

    Your wall plug is only for 1200 watts, it will get very hot trying it 4800w(flames hot). I am surprise it does not require 220/240 volt circuit. A picture or make and model of shower heater will help.

    More information, please. Update your post with a model number or photos. That's a very odd set of specs. Most appliances that draw 50A are 240v. They certainly won't have a standard plug that would interface with a bathroom outlet. #danger #unregulatedgizmo

  • only have a cold water feed ... what does that mean? ... why is it not possible to run a hot line?

    Can’t get there from here. Water heating takes way more power than common sockets have. Nov 17 '21 at 22:33

The thing draws 50A. There's no way it will work on any circuit that wasn't designed to supply (at least) 50A. So that means a separate cable back to the breaker panel, and a dedicated breaker. No magic stabilizer is going to get around that.

The only alternatives are going to be impractical, such as installing a large generator in the shower room.

    It shouldn’t draw 50A at ~120V; at 4800W it should be 40A - needing a 50A circuit after 20% derating.
