All the numbers match on my existing one (440 vac, 50/60 hz, +-6%), except for mine has the number 40uf/5uf instead of 45/5 ... will this one work?

A 55 Micro Farad cap will most likely run fine in your unit.. Capacitors work like batteries on start-up of the motor where extra electrical energy assists the unit in overcoming the latency of the motor to start. Capacitors charge at different times depending on capacity. Typically it uses 5 time constants for a capacitor to charge and discharge. All this means that a small cap will charge faster than a large one but means little to the user if they are not using it as some part of a timing circuit. The Booster Supco Cap adds extra energy on startup so the unit gets that extra electrical push. This is a very simplified answer to a somewhat lengthy Study of CAPs in EE courses and how they are used and work.

Where do I buy the wires to hook it up? I can't splice on the terminals myself

The wires are already on the condenser unit... If you have a separate capacitor for fan don't use that terminal or vice versa

would this fit C3455R?Thanks

No. PowerWell 45+5 is 2 3/8” Genteq C3455R is 2”

Dose it fit trane xl16i 4ttx6048?

If your your system issue is the compressor does not start once called and the fan does the you have a capacitor problem. Validate the capacitance in your system; 45uf for the compressor and 5uf for the fan then this product will work. The strap and connector is standard.
