Sorry, but I’m afraid this is correct.
The resistors look right in the photo - but without a parts list, I was looking at the circuit diagram. You have drawn a thermistor (temperature-dependent resistor), not a fixed resistor. I suggest you change the diagram (like my diagram in ‘Learn’) so as not to mislead everyone.
This is not good - you will get a very small signal from your c.t. because of the current from the magnetic field around the cable which touches the c.t. on the outside, if it is carrying a large current.
This is exactly where I would put them - directly on the pins of the c.t.
‘Burden’ is the function of the resistor. In the days before electronic instruments, you would use a moving iron ammeter with a 5 A movement, and a c.t. with a 5 A secondary winding. The ammeter is the c.t’s burden or load (like a packhorse - cheval de bât - carries its load/weight - poid).
A normal metal film resistor exactly like the ones you use for R1 & R2. A power rating of 0.1 W is enough (the actual power at 15 A max load, that’s 15 mA burden current & 1.6 V, is 24 mW).
NO! The value, from what you write, is clearly not correct. Disregard that formula, all the numbers are wrong for what you are doing.
To read 5 A rms and assuming you have a “well-behaved” load - which might or might not be true - your burden resistor will be as I wrote earlier: 1.6 V ÷ 5 mA = 320 Ω. To read 0.5 A rms maximum, your burden will be 3200 Ω. And so on.
Are all your c.t’s the same: 5 A : 5mA?
There’s a Niederlands data sheet 5A AC current sensor module | Customers rate us with a 9/10! which claims it is good to 15 A with a 100 Ω burden, but you cannot expect it to be accurate above this.
Give me a list of the powers and type of load for each circuit, and I will try to estimate the value of burden resistor you need. I need to know the type of load so that I can make a better guess at the peak current it will take. If you need to read over a range of 100 ×, you will certainly need different values of burden resistor according to the current each wire carries.
