Why is a shower protected by a 32A MCB?
If the MCB is 32A it would limit the current anyway. If the shower is on High setting it will use 8.5kw to heat the water to temperature set point whether it’s on 1 or 10. An Mcb will not limit current. Other than when it trips then it will limit it to Zero.
What size breaker do I need for a 7.5 kW shower?
The Right Fuse for Your Electrical Shower
|Kilowatt Rating||Fuse Size|
|7.5 kW||40 amperes|
|8.5 kW||40 amperes|
|9.0 kW||40 amperes|
|9.5 kW||40 amperes|
Can you get a 7kw shower?
If “pressure” (flow) is OK on cold setting (even if head is as low as you say), then unlikely to be a restriction in supply (as same single water feed). 7 kw really is very borderline for a decent shower, particularly in the winter months when the water supply temperature is so much colder).
What is a 32A mcb used for?
Typical Uses for Domestic MCBs 32 Amp – Ring Final. The technical term for your power circuit or sockets. A two bedroom house for example may have 2 x 32A power circuits to separate upstairs and downstairs sockets. Larger dwellings can have any number of 32 A circuits.
Can 8.5 kW replace 7.5 kW shower?
4 Answers from MyBuilder Bathroom Fitters A 7.5kw shower can be supplied using a 4mm cable, but for 8.5kw, you will need at least 6mm cable. Changing the fuse/circuit breaker would allow the shower to work but the cable could overheat and presents a fire risk.
Can you still get a 7kW shower?
Is a 7.5 kW shower any good?
7.5kW and 8.5kW electric showers If your household hosts a smaller water tank or an unreliable water supply, this range of kW rates will probably suit you best. 7.5kW and 8.5kW shower rates require less power so the gentler flow of water will mean your shower is unlikely to ever run cold.
Can I replace a 7.5 kW shower with a 8.5 kW?
What is a 6 amp MCB used for?
Typically, a circuit breaker or fuse of 6 amps is used. The conductors in lighting cables therefore need not be very thick. One 100 Watt bulb uses less than half an amp as shown below. Therefore, a 6 amp mcb could safely protect a circuit feeding more than ten 100 W bulbs.
How many sockets can you have on a 32A Ring Main?
50% of maximum point of utilization and 40% of remaining points are used to calculate the diversity of a sockets circuit. You can only have a maximum of 4 sockets for a 32a ring.
Can you still get a 7kw shower?
What is the difference between 7.5 kW and 8.5 kW shower?
7.5kW and 8.5kW electric showers 7.5kW and 8.5kW shower rates require less power so the gentler flow of water will mean your shower is unlikely to ever run cold. What’s more, they’re usually cheaper models to purchase and run.
