Safe distance between capacitor and guardrail
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
A guardrail is classified as a semi-rigid barrier due to its deflection distance upon crash impact (see the HKP article, Roadside Safety (coming soon), for a discussion on barrier categories). A transition section is needed when a guardrail connects to a rigid barrier (e.g., bridge railing or concrete barrier) or rigid object (e.g., bridge pier or sign structure).
