Hi All,

 

Am currently thinking about getting a Spa pool and have a few questions around the electrical requirements.

 

I have kind of arrived at a short list of models I am interested in but note that the models require between 25amps up to one model  that requires 45amps.

 

Obviously I will need to get an electrician in to run a hard wired connection in but I guess my question is, are those kinds of amperage requirements going to be a concern on what is supplied overall to the house?

 

I am just wondering if I can take it as a given that an electrician can just come around and run a new connection through to the Spa pool?

 

 

 

Thanks in advance, we have a couple of electricians coming around later in the week but just eager to find out sooner if its answerable.

As long as you have detailed specs on the model you want and it's possible to get back to a point of supply (switchboard or meterbox if absolutely necessary) it can be done. Assuming you are on a standard supply (60A single phase) or higher. Maximum demand calculations can override the maximum amperage specifications of the spa, just so you know, but will be discussed with your electrician.

Yes, you may only have 40A for the whole house depending on how cheap they were when building.

 

Upgrading it, vector seem to want the same amount that developers have to pay for a whole new install to a new development. Was going to be 14k or so for me to upgrade here to get more power, and that was 10 years or so ago so I can only imagine that its got worse since then. Thats urban auckland down a long driveway with overhead cables.

They have slightly friendlier pricing for urban areas now - around the $2000 mark for a pit to be installed. Won't help with long overheads, but the most common street facing sections they'll do an underground pit for about that

 

Recently had a 150m underground run 3 phase pillar with comms duct for $10k

When did you get the quote? I've had about eight new ones with underground pits like that the last 2 months no more than 2k for the pit install/livening?

And are you in an urban area? or semi/rural? That makes a difference to them as well with transformer loadings

Our pool reseller arranged the electrical for our installation. It is on its own circuit with circuit breaker and RCD.The cabling was run condiuted under the house to the outside board. The cost of the electrical work was circa $600.

Yeah, but that is based on the housefeed being adequate,

 

if the OP only has a regular 60 amp connection, a 45 amp pool is gonna cause major overloading issues and require a connection upgrade... hence the $K quotes being thrown around...

 

I think the first port of call is to get a Sparkie to determine what the current connection/board capacity is.. and what spare capacity there is ..

Didn’t realise it was so technical. Our spa pool just plugs into a standard wall plug inside the house. Extension cable runs outside and to the spa pool.

Yes neither did I, the electrical part was actually an afterthought for me, I knew some models required hard wiring once they get over a certain amperage but didn't realise that some spa pools can exceed an entire house's supply of power - scary.

i was looking at the Alpine Spa models.

 

 

https://alpinespas.co.nz/spa-pools/munro/ - modest 15/25 amp requirement, not really sure why it lists 15/25...

 

https://alpinespas.co.nz/spa-pools/k2-spanet-system/ - 32 amp requirement, this is the one the wife wants..

 

 

https://alpinespas.co.nz/spa-pools/entertainer-x90/ - this is the beast that requires 45 amps.. but also needs barrier consents, + consent for holding more than 2,000 litres, plus would need to be sunk slightly into a deck or something as otherwise would break the building regulations of falling from a height >1m

 

 

So while I really like that last one, I see the costs just rocketing with everything that needs to be done and now the power draw might be the last straw...and extra connection costs potentially.
