Re: A/C Capacitor Voltage
Just to recap (sorry). You can safely use a capacitor with a higher VOLTAGE rating than required. No problem. You can NOT use a capacitor with a capacitance much more than 10 percent higher or lower than required.
Re: Sub floor radiant heat for primary heat source
Good under floor plates (not the beer can type) will work fine and probably be less expensive any of the manufactured above floor systems provided your R value doesn’t go above 2. Typically, you can get about 20 btus output per square foot at 120* SWT which should be sufficient for a properly insulated house.
We prefer the Rehau double tube plates.

Re: A/C Capacitor Voltage
I've seen capacitors rated for all kinds of voltages
16, 35,50,63,75, 600 etc.

Re: Your thoughts and opinions please
Your curriculum is excellent for a well seasoned person with years of experience as a brush up and review...A full day class, no less. It's a pretty good bet, the class experience will vary greatly. Could it be that this is the client's wish list? Cover all bases AND in 3.5 hours?
Just covering all those points, without anyone asking a single question is rough. I would run my concerns by the client, hopefully he will modify accordingly. All salient points from the guys. Mad Dog
Always assume the old steam boiler was installed wrong, this weeks video
This never happened with the old boiler is phrase I heard often until I started thinking every steam boiler was installed wrong until I proved it wasnt. There is a hidden clause when installing steam boilers that you dont discover until the boiler is installed, You own all the system problems. Hope you enjoy
Re: A/C Capacitor Voltage
That's why I never dug too far into it.
I just automatically buy 440v caps, regardless, specifically Titan HD which say they're made in USA.

Re: A/C Capacitor Voltage
If you need a 370 V capacitor you can use a 440 v capacitor. If you need a 440 V capacitor you can not use a 370 V capacitor. So if you don't know if you need a 370 or 440 then you should use the 440. If you can find the original specification in the equipment docs, and it specifies a 370, the you are good to go.
