When you do anything like this you have to think about the demand of the whole site... it may only have 100A 3 phase which this shower could wipe out nearly 1/6 of
I was just saying that you cannot just think of the individual unit,,, and possible upgrades to its supply/submain without considering the site as a whole.
I get this regularly from a park site when new residents want an electric hob... you can say yes to maybe 1 or 2,,, but you do have to draw a line at some point
Dont worry i would not just change it, i have been down to check all the supply cables from the main distribution board to the meter board at the site, and have a meeting nxt week with the hydro on site to check everything is ok with the plan before changing it. i said to the client as i was not the one who did the intial install i want to know the set up.
i'm still young in this game and will be learning right up to iwhen i retire i assure you of that!
good for you muskrat, just be carful how you word stuff when posting questions, the old skool on here like detail, and get picky if its a little short because they dislike 5WWs / lazy sods and get a little rude :^O
Please don't be put off, post carefully and you will find a lot of knowledge and help.
