Workshop wiring

[robin colemanParticipant @robincoleman77853]

I am having some electrics put in the workshop how many amp does a small pillars drill use and a small watchmakers lathe they all runn off a 13 amp plug but I doubt if they use a full 13a

[Craig BrownParticipant @craigbrown60096]

Without knowing the rating of the motors fitted to each its hard to say for sure but a watchmakers lathe and pillar drill, sized for similar work, I think it would be safe to say they will be below 3A each. I assume both won’t be used simultaneously so that’s also a consideration

[Peter Cook 6Participant @petercook6]

Pillar drill will be <500W so < 2 amps. Watchmakers lathe will be <1 Amp unless you have fitted an enormous motor!

My workshop (LED Lighting, SX1LP mill with DRO, Taig lathe, couple of watchmakers lathes, filing machine, belt grinder, dremmel, bench grinder, etc, etc, etc) runs off a 13amp fused spur from the house with no problems. You only use one machine at a time typically. Most power hungry device I have is a 2Kw oil filled heater.

Ok thank you I am going to separate the sockets lights etc on a consumer unit it runs from a fused spur to the outside plug for the spar but is never on permantly the only device which may draw power is the arc welder which i occasionally use in the workshop if desperate but I mainly run that off a house socket.

I would suggest that if being done professionally that you consider 16 amps as the minimum from the house or a ring main and lighting circuit. That will give you plenty. The items you have mentioned will be about 3 amps running, but starting or any heating or a small welder will soon add up. Noel.

AH SO, now you mention a welder, this may well exceed 16A ! You should have told us this first ! I would talk to the electrician you intend to sign it off as he will know better than some of us.

I have a background in electro mechanical engineering a d electronics and made my first tv from parts when I was 11 so a bit of wiring should be ok I will just get an electrician to sign it off.

When I had my bungalow rewired I had a dedicated 40A supply taken to my workshop.
