I have a Hayward 2.5HP pool pump that had a bad capacitor after 5 years of running. A service guy came and found the capacitor connectors burnt out, so he replaced the capacity with a 55.0 +/6% 370 VAC/B capacitor. After a few weeks, it burnt out the wire and the plastic connector was melted. I rewired it and added electrical tape and a week later it burnt out.
I had a second pump and decided to use the capacitor from that. That's when I found out that the pump needed a 50.0uF +/6% 370VAC/B NOT a 55uF capacitor. I've just ordered a new one for the pump but I wanted to check to see if using a 55 instead of a 50 uF capacitor would lead to the wires at the capacitor connection constantly burning out or if there is something wrong that's causing this issue and changing the capacitor to a 50uF won't help.
