Extension Reel - watts questions eekkk

vaio

yep, cable jointers tend to be on the bulky side, it's an occupational qualification

In 40 years I've only seen cables spiked twice and the last, maybe 5 years ago, was hydraulic rather than cartridge operated.

Both the ones I've seen were installing HV cable branches for new transformers and I have to admit a small part of me was secretly hoping they had got the wrong cable and looking forward to the firework display.

More recently we've been getting new branches put in for little 400/3 pumping stations and the EDF jointers doing those did maybe 50% of them live with of paxolin/nylon wedges and insulated tools. Not something I'd choose to do for a living but always pleasing to watch someone practiced at their trade, they make it look easy.

Meanwhile, back on topic......

If you want to see the results of overloading an extension lead, have a read of http://www.esc.org.uk/fileadmin/user_upload/documents/industry/product_safety/Extension-lead-test-report.pdf

The chances are, the fuse won't blow. But the plug might melt around the live pin.

WOW - I didn't follow that very well!

So will I be okay to use two leads as quoted earlier with RCD.

One will run a fryer 2000 Watts and

One will run a fridge 100W and another firdge 200W, and a warmer 800W

Watts,

Anyone know if that;s okay?

Yes, that will be fine. Make sure you take the supplies from two separate mains ring circuits e.g. upstairs and downstairs.

Your power figures have changed since your original post? The warmer was 700W and the fridge was 1kW!?

P.S. Don't forget that you have to press the reset button every time you plug the RCD in - in case you're wondering why it doesn't work!

For that amount of amps, using two different sockets on the same ring main should be fine (a ring main is usually 30A and this is much less). Meanwhile, trailing a longer cable to a further away second socket on another circuit, which may well be upstairs, could be more dangerous for no real electrical safety benefit. Keep in mind these cables if pulled accidentally by someone's foot or whatever will be pulling on very hot appliances that could fall over unexpectedly.

Without knowing the loading of the circuit at the time, you cannot assume that it isn't near capacity.

The example of upstairs and downstairs was given however, in an earlier post I mentioned looking for two separate mains circuits by checking the consumer unit. These could be downstairs.

I agree running the cable from upstairs isn't ideal however, the cable could be pulled whether the cable runs on the ground from downstairs or upstairs.

I'm sure the OP will secure the cables properly and keep them well away from walking areas/pets.

Hi thanks again.

I will make sure the cables are safe and they won't have to trail far.

We are using a public house, so I expect they would be able to run these things as they have sound systems and so on.

would of advice, if anyone is going to walk anywhere near them the get flexible cable protection in case one is damaged or trips someone. get public liability insurance and as stated before make sure you uncoil the cable completely or your gonna end up with a nice inductor


just edit to add... insurance etc is because two years ago at a event i tripped over a cable laying in longish grass and couldnt see it! one fractured arm and £4k compensation from someone that wasnt insured! dont risk it
