Power cable

[Bob0987]

Hi

I mostly use a Bose L1 compact with T1 tonematch for 90% of my gigs.  I also have a second L1 compact and an L1 model 2 with B2 bass which I use occasionally for larger venues.  I carry a 3 socket trailing socket extension to power whichever combination I’m using.  What is the thinnest lightest cable I can use safely and without compromising performance on the extension?  Length is 3 or 4 metres.  I also have a couple of 2 socket extension reels which are 10 metres and have 3x1mm cable rated max 10 amps when unwound or 3 amps when wound.  It’s never happened before but in a worst case scenario where I needed to use everything (maybe outdoor wedding) ie wall socket > 10m extension reel > 10m extension reel > 4m extension > 3xL1’s and mixer am I likely to have problems?  (I want thinner cable so it fits in the L1 compacts cover pocket with other leads)

Hi Bob,

For 4 meters and a couple of Compacts, personally I would not use les than 14 ga. though 16 might be acceptable.

When running long long distance it is advisable to use Minimum 14 ga.

Mixing ga. in long runs is really not advisable unless the smallest is capable of operating safely for the complete distance. Multiple connections will make the run less efficient so having excess carrying capacity is a good thing.

I tend to use heavier gauge rather than lighter as a safety factor, even if it is not specifically called for. If wire is too light heat might be the first symptom you notice even if the equipment seems to be working flawlessly.

O..

Ok thanks for reply.  I’m in uk and using 240volts, not sure what difference that makes if any?  I do also have a bigger extension which I’d take if I knew in advance I might need it.  I’ve not noticed the cable warming before but as I said I mostly just run one L1compact and one T1 with a 4 metre 10 amp extension.  I wondered if sound quality would be compromised in worst case scenario as well as safety?

Hey Bob,

Welcome to the forum! Thanks for joining us. 

Regarding sound quality: setups with longer cable runs are more susceptible to interference, which could result in a hum or buzz added to the source signal. Avoid having power cables and audio cables running side by side, ideally keeping them at least 8 inches apart. If it's necessary to cross the cables, it's best to do so at 90-degree angles.
