Beginners Low Voltage Electrics

This session will be an overview for beginners, aimed at people with no experience of low voltage electrical wiring and safety. With a few basic principles, it is possible to DIY low voltage batteries and wiring safely. Learn to use testers and multimeters. We will discuss what the numbers actually mean.

Blake from Green Dragon runs his stage at events from solar panels and battery power. He has been wiring up small scale DC systems for the last 15 years. Solar panels are cheaper now and easily in reach of anyone who wants power off-grid. Green Dragon is powering the whole site including kitchen blenders and site lighting.

Risk assessment

Risk: 12V lead-acid Battery
Lead-Acid batteries contain acid that seeps out onto the tops.
Overcharged batteries generate hydrogen gas and can explode.
Shorted batteries can explode.
Shorted batteries cause the metal thing shorting them to melt/vaporise/explode
Control: Battery terminals will be covered when not being accessed.
Control: Battery used will be stationary and wiped down.
Control: Customers will wash hands after touching battery.
Control: Part of the workshop will involve battery handling, storage and safety
Control: Battery will be charged to manufacturers specs by a dedicated CC/CV power supply.

Risk: Burns from Soldering iron or heat gun
There is a risk of minor burns from these devices.
Control: First aid kit with Burn Gel dressings. Heat used under supervision by Green Dragon staff only. Fire Extinguisher.
