For running power tools on site, choose a petrol generator rated at 2–3× the combined running wattage of all tools you will use simultaneously — this headroom handles motor start-up surges without tripping. Multi Trade Combines stocks Alpha petrol generators in Guwahati, sized from small 1 kVA portables to larger 5–7 kVA site sets.
Every motor-driven power tool (drill, angle grinder, circular saw, air compressor) draws 2–3× its rated running current at start-up. A 2,000 W angle grinder may pull 4,000–5,000 W for the first second as its motor spins up. If your generator's rated output is close to the tool's running wattage, this surge will stall or damage the generator.
The safe rule: generator output (W) ≥ 2× sum of running watts of simultaneously-used tools. For a typical site kit — one angle grinder (2,000 W) + one drill (800 W) + site lighting (200 W) — running total is 3,000 W. You need at least a 5,000 W (5 kVA) generator. See our generator KVA sizing guide for a detailed calculator.
Petrol generators (like the Alpha A2200) are lighter, cheaper to buy, and easy to start — ideal for sites that move frequently and don't need continuous all-day generation. The A2200 produces 2 kVA and suits a single drill or grinder plus lighting.
Diesel generators have better fuel economy and longer service intervals — preferred for sites running 8+ hours per day where fuel cost matters. For a large construction site with multiple power tools, a 5–7.5 kVA diesel set is cost-effective despite the higher purchase price.

Assam's humidity and monsoon conditions demand extra care with generators on site: always use a rain canopy or generator tent during the monsoon months, ensure the exhaust is directed away from enclosed work areas (carbon monoxide hazard), and use only the recommended grade of petrol or diesel for the prevailing temperature. Keep a spare air filter and spark plug on site — choked filters are the most common cause of poor generator performance in dusty construction environments.

A 4–5 kVA generator is the minimum for running a 2,000 W angle grinder and an 800 W drill simultaneously with headroom for motor start-up surges. Our Alpha 5 kVA generator suits this load. WhatsApp us for a quote.
A 2 kVA generator will run site LED lighting (200–400 W) and a standard 13 mm drill (500–800 W) comfortably. For angle grinders or larger tools, step up to a 4–5 kVA set to handle start-up surges safely.
