Plug-in vs hardwired spas: which power supply do you need?
Understand the difference between plug-in and hardwired spas, what to check at your switchboard, and when to involve a licensed electrician before you buy.
By Spas Online Australia ·
What's the difference?
A plug-in spa runs from a suitable power outlet. A hardwired spa is connected directly to a dedicated electrical supply rather than plugged in.
Our current range includes 10 Amp and 15 Amp plug-in models, a model that can be configured as 15 Amp plug-in or 25 Amp hardwired, and a number of 32 Amp hardwired models. The exact requirement is listed on each product page, so check it for the model you're considering.
Don't assume your outdoor socket will do
"Plug-in" doesn't mean every spa suits the socket you already have. A 15 Amp plug has a wider earth pin than a standard 10 Amp plug, so it won't fit a standard 10 Amp socket, and a 15 Amp spa may need a dedicated outlet installed first.
Look at where the outlet sits, too. Ask your electrician whether it's suitable for the spa, and how far it is from where the spa will go.
What to ask your electrician before you order
A quick site visit before you buy can save a surprise later. Take the spa's published power requirement and ask:
- Does my switchboard have capacity for this supply?
- Will the switchboard need any upgrades?
- How will the cable reach the spa's position, and how far does it need to run?
- What will the electrical work cost, and how much notice do you need?
Include electrical work in your budget
Electrical work is separate from your spa price, and the cost depends on your property, so we can't estimate it for you. Get a quote from your electrician early, particularly if you're choosing a hardwired model or your switchboard is far from the spa's position.
Who does the final connection?
Final connection must be done by a licensed electrician. Plan this alongside your delivery so the supply is ready when the spa is in position.
Choosing between them
Start with the spa that suits your space and how you'll use it, then check its power requirement against what your home can supply. If two models suit you equally, the electrician's advice and quote can help you decide. You can filter our range by power type when you compare spas.
