What is the Seaward Solar 388A688 PV150 Fused Test Lead?
The Seaward Solar 388A688 PV150 Fused Test Lead is a dedicated MC4 fused test lead designed for UK solar PV electricians and installers carrying out commissioning, maintenance and fault-finding on photovoltaic systems. Rated at 1000V DC and 15A, it provides a safe, controlled connection when testing live PV arrays using the Seaward Solar PV150 Installation Tester.
Purpose-built for professional solar testing, this fused lead protects both the user and the tester from overload conditions commonly encountered in PV environments. Its robust insulation and clear red polarity identification make it ideal for routine use on domestic and commercial solar installations.
How does the Seaward 388A688 support safe solar PV testing?
By integrating a 15A fuse within the lead, the 388A688 helps manage fault currents and reduces the risk of damage to your PV tester during live measurements. The secure MC4 connection minimises accidental disconnection, supporting consistent readings when working on high-voltage DC systems. Compact and durable, it’s a reliable replacement or spare lead for engineers who depend on accurate solar PV test results.
