Maximum distance between poles?


Recommended Posts

Today we were at PEA applying for a temp meter for construction. From the metered pole to where we plan to build is about 75m. Is there a standard distance between poles for stringing wire? PEA said the distance is up to me.

Plan on having 30 amp meter upon house completion is that suitable for running a residential home with several AC units and occasional welding in a workshop?  

 

Thanks

I believe I read 100m suggested max somewhere for LV (Low Voltage 220-230VAC domestic service). Our service pole is 3 meters from the house then 60 meters to the next pole.

 

You may want to take in into consideration

The type of conductor used

The maximum permissible tension on the conductor.

The maximum conductor sag

Environmental parameters (wind load, impact of weather, vegetation growth/impingement)

Secondary use of poles: stringing copper or fiber for Internet, WAT or Headman speaker cables

Our poles are 22m apart, mainly because the distance from road to house is 44m (we have 3 poles due to the route taken down the edge of the property). Looking at the sag between poles I would say 30-35m would be the limit for self-supporting wires.

 

For 75m I'd be looking at 4 poles:- 

<street> 25m <pole> 25m <pole> 25m <house>

of course direction changes need a pole too, so sketch out how you intend routing your supply then put poles in sensible places.

 

Probably best to consult your pole contractor, ours were put in by PEA chaps moonlighting.

 

Your 30/100 meter (22kW) should be adequate for a reasonable large home. We get along just fine on a 15/45 (including welding). Have PEA said they can provide a 30/100?

 

Best to do a rough and ready load calculation, is 3-phase available at the road?

Did you mean to say 15/45 ?

Honestly I know little about electrical. However when we applied for the temporary meter they asked if we wanted 15 or 30 amp. She said most people get 15 amp for construction purposes which makes sense.

I assumed he meant 30/100 which are not always available. Hence my suggestion to do a load estimate.

How do I do a load estimate? I know we will have 5 AC but not running at the same time, fridge, freezer, 3 PC's and a couple of ceiling fans. No pool but a garage with occasional power tools and low amp welding.

I will ask PEA if 3 phase is available.

I can do it for you no problem, I can make some assumptions but we can get a ball-park idea.

 

Do you envisage on-demand water heaters? How many? How big (do you like volcanic showers at Niagra flow rates)?

How about cooking? Electric oven and/or hob (cooktop)?

Water supply - well pump?

 

I'll assume low-energy lighting.

 

A house floor plan would be handy to size the A/Cs.

 

Any plans for solar? Backup generator? It's much easier to design these in at this stage even if you don't implement immediately.

Wow you make some good assumptions I didn't think to add.

Do you envisage on-demand water heaters? How many? Yes 4

How big (do you like volcanic showers at Niagara flow rates)? Volcanic yes flow rate low to save water. 4000 watt

There will be electric oven but stove will be gas.

The 3 bedrooms and Multipurpose Room will have 12 000 BTU AC Inverter Type. However I will try and make this house very well insulated. The living room Is large and we may use fans only the kids and I tend to spend time in our rooms/office or outside.

No backup generator planned but I was thinking about solar. I'm still not clear if it is worth it or the legality, there seems to be a lot of debate surrounding solar.

Thanks for your help.

The meter you should ask for rather depends on the final supply you want as if you are going to use a 30/100 supply then a temporary meter that size will not need to be changed when you on to the permanent tariff.

You will not get Volcanic temperatures for about 3+ months with a 4,000 watt unit, you will need 6,500 W or higher, unless you are getting 25+ Cold water year round

It's what we do 🙂 

 

Anyway, I'll get back on this later, I just got a large stack of cable test results to look at (fibre, UTP and power) looking at which actually pays the bills 🙂

We have a 4000 watt unit now and it get very hot if the tap isn't opened all the way. Otherwise my kids will stay in the shower until the storage tank runs dry.

If you are happy with the current unit and you are in the same area great.

Let's not get into the "my heater is bigger than yours" discussion again.

 

No kids, but we have grandkids to stay, when they do the power bill doubles with loooong showers and aircon usage.
