It’s not unusual that solar photovoltaic (PV) systems would require
fuses – after all, these installations can carry substantial electrical
loads, so overcurrent protection is critical to their safe operation.
What is remarkable, though, are the conditions under which PV panels,
their conductors, and their wiring can operate.

Guess What? Fuses Still Matter
Up until three years ago, I lived with a couple small boxes of spare
fuses that sat on top of the water heater in the basement, ready to be
drawn from should the rare combination of, say, the toaster and
microwave operating at the same time happen to shut down power to the
kitchen.

Switchboards: The Cornerstone of Power Supply Dependability
Switchboards are critical to the dependability of any electrical power
installation because they represent that pivotal point at which incoming
power supply is divided into separate circuits, controlled and
protected by fuses and switchgear, metered, and then divided into a
number of functional units for its given applications. In general,
switchboards distribute power to transformers, panelboards, control
equipment, and to system loads.
