    <p>What is the brand and model of the disconnect? Temp ratings of
      the terminals?  I've definitely had fuse holders not make good
      contact with the fuses and burn the fuses at one end, instead of
      in the middle.  Have you looked at it with a Thermal imaging
      camera when its operating to see if its hot on one end of the
      fuse?  <br>
    </p>
    <p>Second, depending on the temperature it would be hitting inside
      the enclosure in the sun, you could be exceeding the rating of the
      #6 conductor.  Assuming terminals rated at 75C, then from 310.16,
      a #6 is rated 65 A, but derate for temperature of 114F inside the
      enclosure gets you to .82 x 65 = 53.3, which is a bit less than
      the 54.45 that Dave just calculated for continuous duty.  <br>
    </p>
    <p>What color is the disconnect painted?  any chance of painting it
      white?<br>

                                                          on the roof
                                                          and found that
                                                          the installing

                                                          right there.
                                                          This was a

                                                          <p>What has
                                                          been happening
                                                          is one of the
                                                          BR220 branch
                                                          circuit
                                                          breakers and
                                                          the combine
                                                          CH240 breaker

                                                          center have
                                                          been tripping
simultaneously. It has happened about four times in the last 6 months.
                                                          It was always
                                                          the same
                                                          branch circuit
                                                          breaker, so we
                                                          kept
                                                          investigating
                                                          that string,
                                                          checking the

                                                          trunk cable,
                                                          and cap, etc.
                                                          Finally we
                                                          swapped out
                                                          the BR220

                                                          forward 4
                                                          weeks, and we
                                                          got another
                                                          call. This
                                                          time a
                                                          different
                                                          branch circuit
                                                          breaker and
                                                          the main
                                                          breaker
                                                          tripped
                                                          simultaneously.
                                                          We checked
                                                          that branch
                                                          circuit and
                                                          could not find
                                                          any fault. It
                                                          seems unlikely
                                                          that two
                                                          branch circuit
                                                          breakers would
                                                          be faulty, so
                                                          we have now
                                                          switched out
                                                          the CH240 main

                                                          confident in

                                                          resolution and
                                                          I have my
                                                          fingers
                                                          crossed. If

                                                          anyone have
                                                          any
                                                          suggestions on
                                                          another
                                                          diagnostic
                                                          step? These
                                                          intermittent
                                                          problems are a
                                                          major hassle.
                                                          One thought I
                                                          had was to
                                                          switch to a
                                                          supply side
                                                          interconnection
                                                          with a fusible
                                                          disconnect.
                                                          Maybe the
                                                          intermittent
                                                          fault would
                                                          blow one of
                                                          the two line
                                                          fuses so at
                                                          least I could
                                                          narrow it down
                                                          to which line
                                                          the fault is
                                                          on if there is
                                                          in fact a
                                                          fault.</p>

                                                          two other
                                                          tripping
                                                          breaker issues
                                                          with Enphase
                                                          systems in the
                                                          past. Neither
                                                          of them were
                                                          systems I
                                                          installed. One
                                                          turned out to
                                                          be branch
                                                          circuits that
                                                          were not
                                                          properly
                                                          paired up and
                                                          landed on
                                                          different
                                                          breakers.
                                                          Another time
                                                          we had an
                                                          inverter with
                                                          an internal
                                                          fault which
                                                          eventually"blew

                                                          loud popping
                                                          noise and
                                                          smoke
                                                          billowing out
                                                          of it. That

                                                          trip breaker
                                                          multiple
                                                          times. This
                                                          case seems to
                                                          be unrelated
