    Isoboost transformer: how useful?

    So here is my take...... A/C units.... even the most sophisticated newer models will accept voltages between 187 and 253 VAC for a 208-230 supply. As mentioned earlier, when the voltage goes down, more current is drawn. When you are at the bottom of that range, a brownout/surge can have...

    Help me to find what's wrong!

    sounds like you may have a corroded cable connection, check connections not only at batteries, but at the other end, at the dc panels, etc. A simple digital volt meter should point out the problem for you. start at the batteries, checking voltages, then at the busses in the DC panel, at that...

    Air conditioning

    +++++1 DO Not let a technician put stop leak in one of these systems. It's the same analogy as radiator stop leak, transmission stop leak..... it just doesn't work. If the unit is more than 10-15 years old, more than likely it will have a leak in the coil. Depending on how much it is ran when...

    AC rotary selector switch

    According to the Kraus and Naimer website this is a 2 pole switch, meaning 2 inputs. Be sure that any switch you get is a break before make type switch. Just my $.02.

    Galvanic Isolator

    If my memory serves me correctly, the reason for 25kohms is the resistance across the polarity indicator.

    Northern Lights Gen Set High Temp

    If we really looked we would probably find several connections that have corroded or worked loose one way or another. Many (or should I say most) of the electrical issues have to do with ground connections. Just hard to keep up with it all. An anti corrosion compound helps to an extent, and any...

    I can look up the ABYC standard to check, but I would, that's just my preference.

    Installing new AC System 2 Questions

    If you are using only 1 pump, it should have a capacity of 1,000 to 1200 GPH. That would be plenty of flow when both units are running at the same time. Water will flow through both units, even though only one is operating. 3/4" outlet on the pump (in most cases) "Tee"d to (2) 5/8" OD hoses, 1...

    Installing new AC System 2 Questions

    In boats with multiple systems running on one seawater pump there is most likely a Pump Relay to receive a signal from each system to tell the pump it needs to run...That is unless it has been bypassed and the pump runs 24/7 from the breaker ( I see this done fairly often) Lets start with the...

    Installing new AC System 2 Questions

    +1 In order to accomplish this you will need a pump controller. It takes the signal from each AC unit to turn the pump on when there is a call for cool (or heat). Pump and fittings must be big enough to provide proper water flow if both units should call at the same time. Pump output can be...
