How long can you run the cables for video and power?

Hey guys,

 

I know I really shouldn't ask, but what the heck is 'knob and tube'.

 

On behalf of any other Brit colleagues that are chuckling their socks off in blissful ignorance, I should perhaps mention that the term 'knob' does have quite another meaning, this side of the pond

 

Uhh. Same here. LoL.

 

Knob and Tube describes an old method of installing electical service in buildings. It was back in the day before ground wires.

 

Here's a good diagram:

Many thanks for that C7 in CA,

 

Never come across that one before (I've led a very sheltered life).

 

I suppose the modern equivalent would be pyro cable, where the live and neutral are mineral encased inside an outer copper tube. Fortunately, it's not the kind of cable we need to use too often for CCTV work.

 

hey herminshs,

 

Go easy on the knob jokes, it's not good for the blood pressure
