Does anyone make a shower priority control for THREE showers, that permits of any TWO showers being used at the same time, but NOT all three.
3 phase 100 amp supply. Showers each 40 amps.
L1-----------3 showers, showers one and two to take priority, shower three disabled if BOTH the others are in use, but permitted if only one other is in use.
L2------------as L1
L3-----------2 showers, either or both can be used, but if both are in use, the output intended for the third shower is turned off, this to supply immersion heaters.
I appreciate that one would probably "get away" with 3 showers each of 40 amps, on a 100 amp supply, but in this case with significant other load I am a bit uneasy about two showers, three no way! This is an existing installation with a history of operating the cut out fuses.
The water supply is confirmed as ample, boosted supply from a large cistern.
