Day Fuse and Night Fuse for Hot water heater
Hello, I am attempting to replace my water heater. I've got to the point where I want to hook my home's wiring to the water heater. However, on my old water heater and home wiring, I have a Red, Blue, Black and a Yellow wire. On my new water heater I just have a red and black wire.
I'll be trying to include some schematics that's on the fuse panel if that would help.

Okay, here is the picture of my old school fuse box...
It looks like the Red and the blue come off of something called a day fuse. The red and the black come from something called a night fuse. They both are two separate fuse packs.
New Heater: 5500 watts 240v

That type of setup would require a special smart meter or a separate water heater meter.
Do you have either ?

Nothing that I am aware of.
I was thinking of just hooking up the red and black and hooking up the corresponding fuse. But that can't be a long term solution. Do you think it'd be safe to do so?

Can't quite read the diagram. Maybe a close up pic of just the diagram.
I would think that if you don't have a second meter or timer.... then the day fused circuit would be used. That would mean the blue and yellow wires

So, I just ran my multimeter to the fuse block. As of now, 1030 Eastern, the day block is active. The blue and the yellow. Red and black, the night block, is reading 0v.
When I read the diagram that actually makes sense as well. I wonder if I should check on it during another time to see if anything changes.
I'll provide a closeup tomorrow evening.

How many wires (at the far end of the cable from the fuse block) enter the old water heater and what colors are they?
If more than two, what is the voltage across each of the possible combinations of wires taken two at a time, at the water heater?
?
