{"product_id":"copper-busbar-25mm-x-3mm-300-amp","title":"Copper Busbar - 25mm x 3mm - 300 Amp","description":"\u003cp\u003eThe AllSpark Copper Busbar (25mm × 3mm) is a heavy-duty power distribution bar rated at 300 amps continuous, built from solid high-conductivity copper for minimal voltage drop and maximum current-carrying capacity. At 25mm wide and 3mm thick, it delivers an optimal cross-sectional area of 75mm² — engineered to handle the high-current demands of dual-battery systems, lithium battery banks, inverters, and DC-DC chargers without overheating. The bare copper construction ensures the lowest possible contact resistance, while pre-drilled bolt holes provide secure, rattle-free terminations suited to the vibration and corrugation of Australian outback tracks.\u003c\/p\u003e\n\u003cp\u003eDesigned for caravanners, 4WD tourers, and RV builders who demand a clean, professional electrical installation, this busbar is the backbone of any serious 12V or 24V off-road power setup. Whether you're consolidating multiple battery terminals in a caravan's power management bay, distributing load across a motorhome's auxiliary systems, or building a dual-battery tray in a Land Cruiser or Patrol, the AllSpark BB-25X3 provides a reliable, code-compliant connection point for all positive or negative cable runs. Its compact footprint fits easily into battery boxes, cable trays, and custom steel enclosures — making it a favourite among experienced auto electricians and self-builders fitting out for extended off-grid travel across Australia.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSolid high-conductivity copper construction rated at 300 amps continuous current\u003c\/li\u003e\n\u003cli\u003e25mm × 3mm profile with 75mm² cross-sectional area for minimal voltage drop\u003c\/li\u003e\n\u003cli\u003ePre-drilled bolt holes for secure, rattle-free terminations on corrugated roads\u003c\/li\u003e\n\u003cli\u003eCompatible with 12V and 24V systems — suits dual-battery, lithium, and inverter setups\u003c\/li\u003e\n\u003cli\u003eCompact design fits battery boxes, cable trays, and custom RV power bays\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AllSpark","offers":[{"title":"Default Title","offer_id":56393083977894,"sku":"BB-25X3","price":65.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/4688\/6566\/files\/BB-25X3.jpg?v=1776471162","url":"https:\/\/campingaustralia.com.au\/products\/copper-busbar-25mm-x-3mm-300-amp","provider":"Camping Australia","version":"1.0","type":"link"}
