How to choose Mercury products

For cable, choose the type and conductor size for the job, and LSZH where the building requires it. For extension reels, fully unwind the reel when drawing high power. For inverters, add up the watts of everything you will run at once and choose a model rated comfortably above that. Not sure? Call 01902 902251.

Mercury questions

Who makes Mercury products?

Mercury is a brand of AVSL Group Ltd, based in Trafford Park, Manchester.

What size inverter do I need?

Add up the running watts of everything you will power at once and allow extra for devices with a high start-up current, such as motors and pumps.

Why should I unwind an extension reel?

A wound-up reel can overheat at high loads. Mercury reels with a thermal cut-out switch off if they get too hot, but the safe practice is to unwind fully for heavy loads.
