3 x 1.5kw heaters on one circuit

[Dave OCD]

Pete it's a fraction under 20 amps, not 30.

You could demolish the warehouse and relocate the business to warmer climes and have no need for the heater.

There's a lot you could do but I expect, like me, you have a customer on a budget and are trying to give them something that will work, is safe and is compliant.

What you are suggesting appears to fit those criteria.

Would be very awkward but could make it a ring, the cable is run above ceiling tiles but runs through insulation which is a problem

Some things are not as difficult as you think they are going to be.

What Voltage are you using?

If that's the case then a thorough assessment of the installation method is needed to ascertain the derating required.

A return leg may be the best route, gives more wiggle room and peace of mind.

So it is my bad math was never my strong subject lol

That’s what I was thinking
But I think I’ll just go for 4mm radial with 13amp switched fused Spurs at each heater

 

[Dave OCD]

No worries Pete. We all make a mistake now and then.

The invoice for the design consultation will follow shortly.
